    Plasma waves in the magnetosphere scatter electrons, causing them to precipitate into Earth’s atmosphere, imparting their temporal characteristics to diffuse auroras. In a case study of conjugate radar and satellite observations, we demonstrate a close and unprecedented association between enhanced electrostatic cyclotron harmonic wave activity in the magnetosphere and the appearance of meter-scale plasma turbulence a few seconds later in the lower ionosphere on nearby magnetic field lines. Such direct structuring of the ionosphere carries implications for our understanding of space weather. Published by the American Physical Society 2025

    Abstract We have developed an optical photon-counting imaging system, IMONY, as an instrument for short-scale time-domain astronomy. In this study, we utilized a Geiger avalanche photodiode array with a $4\times 4$ pixel configuration, with each pixel measuring 100 µm. We developed a dedicated analog frontend board and constructed a data acquisition system with an FPGA to time-stamp each photon with a time resolution of 100 ns. We mounted a prototype model of the system on the 1.5 m Kanata telescope, intending to observe the Crab pulsar and conduct joint observations with the Iitate and Usuda radio telescopes in Japan. We successfully demonstrated that IMONY could image the Crab pulsar as an expected point source and acquire the well-known pulse shape. We found that the time lag between the optical and radio main pulses was $304\pm 35$ µs, consistent with previous studies.

    Abstract The Jupiter Icy Moons Explorer (JUICE) is a European Space Agency mission to explore Jupiter and its three icy Galilean moons: Europa, Ganymede, and Callisto. Numerous JUICE investigations concern the magnetised space environments containing low-density populations of charged particles that surround each of these bodies. In the case of both Jupiter and Ganymede, the magnetic field generated internally produces a surrounding volume of space known as a magnetosphere. All these regions are natural laboratories where we can test and further our understanding of how such systems work, and improved knowledge of the environments around the moons of interest is important for probing sub-surface oceans that may be habitable. Here we review the magnetosphere and plasma science that will be enabled by JUICE from arrival at Jupiter in July 2031. We focus on the specific topics where the mission will push forward the boundaries of our understanding through a combination of the spacecraft trajectory through the system and the measurements that will be made by its suite of scientific instruments. Advances during the initial orbits around Jupiter will include construction of a comprehensive picture of the poorly understood region of Jupiter’s magnetosphere where rigid plasma rotation with the planet breaks down, and new perspectives on how Jupiter’s magnetosphere interacts with both Europa and Callisto. The later orbits around Ganymede will dramatically improve knowledge of this moon’s smaller magnetosphere embedded within the larger magnetosphere of Jupiter. We conclude by outlining the high-level operational strategy that will support this broad science return.

    Abstract We report a statistical result of electrons inside the loss cone with energies of 67 eV–88 keV using electron measurements obtained in situ by the Arase satellite in the inner magnetosphere around the magnetic equator for 60 months. Loss cone electrons are found with a high occurrence probability from the nightside to the dawnside at approximately L = 6. For 641 eV–88 keV electrons, the high‐occurrence region shifts toward later magnetic local times (MLTs) with increasing loss cone electron energy. The spatial distribution of the occurrence probability around MLT = 22–3 at L = 5–6 is consistent with the calculated average resonance energy distribution of whistler mode chorus waves near the magnetic equator. These results suggest that pitch angle scattering driven by chorus waves plays the main role in electron precipitation in this region.

    Abstract Strong Thermal Emission Velocity Enhancement (STEVE) is a latitudinally narrow, purple‐band emission observed at subauroral latitudes. Stable Auroral Red (SAR) arcs characterized by major red emission, and red/green arcs with both red and green emissions also occur at subauroral latitudes. Characteristics of magnetospheric source plasma and electromagnetic fields of these three types of arcs have not been fully understood because of the limited conjugate observations between magnetosphere and the ground. In this study, we report 11 conjugate observations (2 STEVEs, 7 SAR arcs, and 2 red/green arcs), using all‐sky images obtained at seven ground stations over more than four years from January 2017 to April 2021 and magnetospheric satellites (Arase and Van Allen Probes). We found that, in the inner magnetosphere, the source region of STEVEs and red/green arcs were located outside the plasmasphere, and that of the SAR arc was in the region of spatial overlap between the plasmasphere and ring current region. Electromagnetic waves at frequencies below 1 Hz were observed for STEVEs and red/green arcs. SuperDARN radar data showed a strong westward plasma flow in the ionosphere, especially during STEVE events, whereas the plasma flows associated with SAR arcs and red/green arcs were generally weaker and variable. The STEVE and SAR arc can appear simultaneously at slightly different latitudes and STEVEs and red/green arcs can transform into SAR arcs. These first comprehensive ground‐satellite measurements of three types of subauroral‐latitude auroras increase our understanding on similarlity, differences, and coupling of these auroras in the ionosphere and the magnetosphere.

    Abstract The electromagnetic interaction between Europa and the plasma sheet in the Jovian magnetosphere generates Alfvén waves, ultimately generating auroral footprints in Jupiter's atmosphere. The position of Europa's auroral footprint is a proxy for travel time of the Alfvén waves. We measured Europa's footprint position using the far‐ultraviolet images of Jupiter obtained by the Hubble Space Telescope in two observing campaigns in 2014 and 2022. The measured footprint position indicates a longer Alfvén travel time in the 2022 campaign. We retrieved the plasma sheet parameters at Europa's orbit from the footprint position by tracing the Alfvén waves launched at Europa and found an increase of both mass density and temperature in the plasma sheet in 2022. The Poynting flux generated at Europa is calculated with the retrieved plasma sheet parameters, which suggests the total energy transfer from Europa to its auroral footprint is similar to the case of Io.

    Abstract The submarine volcano Hunga Tonga–Hunga Ha’apai erupted explosively on January 15, 2022, offering a unique opportunity to investigate interactions between the atmosphere and ionosphere caused by Lamb and Pekeris waves. However, the resonance of Pekeris waves has not been previously detected. In this study, we applied a multi-point monitoring approach focusing on the lower ionosphere and atmospheric electric field. Here we show observed oscillations of 100–200 s in manmade transmitter signals and the magnetic and atmospheric electric fields, which were caused by Pekeris waves. However, no corresponding changes with the period of 100–200 s in atmospheric pressure due to Pekeris waves were observed on the ground. A simulation of neutral wind revealed Pekeris waves oscillating near the mesopause, suggesting resonance. Therefore, the oscillation in atmospheric electric field is interpreted that the resonance in the lower ionosphere was projected onto the Earth's surface via a global electric circuit.

    Abstract Pulsating Aurora (PsA) is one of the major classes of diffuse aurora associated with precipitation of a few to a few tens of keV electrons from the magnetosphere. Recent studies suggested that, during PsA, more energetic (i.e., sub‐relativistic/relativistic) electrons precipitate into the ionosphere at the same time. Those electrons are considered to be scattered at the higher latitude part of the magnetosphere by whistler‐mode chorus waves propagating away from the magnetic equator. However, there have been no actual cases of simultaneous observations of precipitating electrons causing PsA (PsA electrons) and chorus waves propagating toward higher latitudes; thus, we still do not quite well understand under what conditions PsA electrons become harder and precipitate to lower altitudes. To address this question, we have investigated an extended interval of PsA on 12 January 2021, during which simultaneous observations with the Arase satellite, ground‐based all‐sky imagers and the European Incoherent SCATter (EISCAT) radar were conducted. We found that, when the PsA shape became patchy, the PsA electron energy increased and Arase detected intense chorus waves at magnetic latitudes above 20°, indicating the propagation of chorus waves up to higher latitudes along the field line. A direct comparison between the irregularities of the magnetospheric electron density and the emission intensity of PsA patches at the footprint of the satellite suggests that the PsA morphology and the energy of PsA electrons are determined by the presence of “magnetospheric density ducts,” which allow chorus waves to travel to higher latitudes and thereby precipitate more energetic electrons.

    Abstract The ionospheres of Jupiter's icy moons have been observed by in situ plasma measurements and radio science. However, their spatial structures have not yet been fully characterized. To address this, we developed a new ray tracing method for modeling the radio occultation of the ionospheres using Jovian auroral radio sources. Applying our method to Jovian auroral radio observations with the Galileo spacecraft, we derived the electron density of the ionosphere of Ganymede and Callisto. For Ganymede's ionosphere, we found that the maximum electron density on the surface was 76.5–288.5 cm−3 in the open magnetic field line regions and 5.0–20.5 cm−3 in the closed magnetic field line region during the Galileo Ganymede 01 flyby. The difference in the electron density distribution was correlated with the accessibility of Jovian magnetospheric plasma to the atmosphere and surface of the moons. These results indicated that electron‐impact ionization of the Ganymede exosphere and sputtering of the surface water ice were effective for the producing Ganymede's ionosphere. For Callisto's ionosphere, we found that the densities were approximately 350 and 12.5 cm−3 on the night side hemisphere during Callisto 09 and 30 flybys, respectively. These results combined with previous observations indicated that atmospheric production through sublimation controlled the ionospheric density of Callisto. This method is also applicable to upcoming Jovian radio observation data from the Jupiter Icy Moon Explorer, JUICE.

    Abstract Recent simulation studies using the RAM‐SCB model showed that proton precipitation contributes significantly to the total energy flux deposited into the subauroral ionosphere thereby affecting the magnetosphere‐ionosphere coupling. In this study, we use the BATS‐R‐US + RAM‐SCB model to understand the evolution of ElectroMagnetic Ion Cyclotron (EMIC) waves in the inner magnetosphere, their correspondence to the proton precipitation into the subauroral ionosphere, and to assess the performance of the model in reproducing the EMIC wave‐particle interactions. During the 27 May 2017 storm, Arase and RBSP‐A satellites observed typical signatures of EMIC waves in the inner magnetosphere. Within this interval, Defense Meteorological Satellite Program (DMSP) and National Oceanic and Atmospheric Administration (NOAA)/MetOp satellites observed significant proton precipitation in the dusk‐midnight sector. Simulation results show that H‐ and He‐band EMIC waves are excited within regions of strong temperature anisotropy near the plasmapause. The simulated growth rates of EMIC waves show a similar trend to that of the EMIC wave power observed by the Arase and RBSP‐A satellites, suggesting that the model can reproduce the EMIC wave activity qualitatively. The simulated H‐band waves in the dusk sector are stronger than He‐band waves possibly due to the presence of excess protons in the boundary conditions obtained from the BATS‐R‐US code. The precipitating proton fluxes reproduced by the simulation with EMIC waves are found to agree reasonably well with the DMSP and NOAA/MetOp satellite observations. It is suggested that EMIC wave scattering of ring current ions can account for proton precipitation observed by the DMSP and MetOp satellites during the 27 May 2017 storm.

    Abstract This is the first report of significant energization (up to 7,000 eV) of low‐energy He+ ions, which occurred simultaneously with H‐band electromagnetic ion cyclotron (EMIC) wave activity, in a direction mostly perpendicular to the ambient magnetic field. The event was detected by the Arase satellite in the dayside plasmatrough region off the magnetic equator on 15 May 2019. The peak energy of the He+ flux enhancements is mostly above 1,000 eV. At some interval, the He+ ions are energized up to ∼7,000 eV. The H‐band waves are excited in a frequency band between the local crossover and helium gyrofrequencies and are close to a linear polarization state with weakly left‐handed or right‐handed polarization. The normal angle of the waves exhibits significant variation between 0° and 80°, indicating a non‐parallel propagation. We run a hybrid code with parameters estimated from the Arase observations to examine the He+ energization. The simulations show that cold He+ ions are energized up to more than 1,000 eV, similar to the spacecraft observations. From the analysis of the simulated wave fields and cold plasma motions, we found that the ratio of the wave frequency to He+ gyrofrequency is a primary factor for transverse energization of cold He+ ions. As a consequence of the numerical analysis, we suggest that the significant transverse energization of He+ ions observed by Arase is attributed to H‐band EMIC waves excited near the local helium gyrofrequency.

    Abstract This paper presents the highlights of joint observations of the inner magnetosphere by the Arase spacecraft, the Van Allen Probes spacecraft, and ground-based experiments integrated into spacecraft programs. The concurrent operation of the two missions in 2017–2019 facilitated the separation of the spatial and temporal structures of dynamic phenomena occurring in the inner magnetosphere. Because the orbital inclination angle of Arase is larger than that of Van Allen Probes, Arase collected observations at higher $L$-shells up to $L \sim 10$. After March 2017, similar variations in plasma and waves were detected by Van Allen Probes and Arase. We describe plasma wave observations at longitudinally separated locations in space and geomagnetically-conjugate locations in space and on the ground. The results of instrument intercalibrations between the two missions are also presented. Arase continued its normal operation after the scientific operation of Van Allen Probes completed in October 2019. The combined Van Allen Probes (2012-2019) and Arase (2017-present) observations will cover a full solar cycle. This will be the first comprehensive long-term observation of the inner magnetosphere and radiation belts.

    <title>Abstract</title> We report on the multi-frequency multi-epoch radio observations of the magnetar XTE J1810−197, which exhibited a radio outburst from 2018 December after its 10-year quiescent period. We performed quasi-simultaneous observations with VERA (22 GHz), Hitachi (6.9 GHz and 8.4 GHz), Kashima (2.3 GHz), and Iitate (0.3 GHz) radio telescopes located in Japan to trace the variability of the magnetar radio pulsations during the observing period from 2018 December 13 to 2019 June 12. The pulse width becomes narrower as the observing frequency goes higher, analogous to the general profile narrowing behavior of ordinary pulsars. When assuming a simple power law in the range of 2.3 GHz and 8.7 GHz, the radio spectrum of the magnetar goes steeper with the average spectral index 〈α〉 ≈ −0.85 for the first four months. The wide-band radio spectra gathered from our observations and the literature suggest that XTE J1810−197 would have a double-peaked spectrum with a valley point in 22–150 GHz, where the first spectral peak implies a gigahertz-peaked spectrum (GPS) feature with a peak at a few GHz. The GPS and the high-frequency peak have been identified in the spectra of other radio-loud magnetars, thus they may be intrinsic features that can give a new insight to the understanding of various emission mechanisms and the surrounding environments of radio magnetars. Our study emphasizes the importance of simultaneous long-term broad-band observations toward radio-loud magnetars to capture the puzzling spectral features and establish a link to other types of neutron stars.

    Abstract The MMX infrared spectrometer (MIRS) is an imaging spectrometer onboard MMX JAXA mission. MMX (Martian Moon eXploration) is scheduled to be launched in 2024 with sample return to Earth in 2029. MIRS is built at LESIA-Paris Observatory in collaboration with four other French laboratories, collaboration and financial support of CNES and close collaboration with JAXA and MELCO. The instrument is designed to fully accomplish MMX’s scientific and measurement objectives. MIRS will remotely provide near-infrared spectral maps of Phobos and Deimos containing compositional diagnostic spectral features that will be used to analyze the surface composition and to support the sampling site selection. MIRS will also study Mars atmosphere, in particular spatial and temporal changes such as clouds, dust and water vapor. Graphical Abstract

    <title>Abstract</title>Pulsating aurorae (PsA) are caused by the intermittent precipitations of magnetospheric electrons (energies of a few keV to a few tens of keV) through wave-particle interactions, thereby depositing most of their energy at altitudes ~ 100 km. However, the maximum energy of precipitated electrons and its impacts on the atmosphere are unknown. Herein, we report unique observations by the European Incoherent Scatter (EISCAT) radar showing electron precipitations ranging from a few hundred keV to a few MeV during a PsA associated with a weak geomagnetic storm. Simultaneously, the Arase spacecraft has observed intense whistler-mode chorus waves at the conjugate location along magnetic field lines. A computer simulation based on the EISCAT observations shows immediate catalytic ozone depletion at the mesospheric altitudes. Since PsA occurs frequently, often in daily basis, and extends its impact over large MLT areas, we anticipate that the PsA possesses a significant forcing to the mesospheric ozone chemistry in high latitudes through high energy electron precipitations. Therefore, the generation of PsA results in the depletion of mesospheric ozone through high-energy electron precipitations caused by whistler-mode chorus waves, which are similar to the well-known effect due to solar energetic protons triggered by solar flares.

    Giant radio pulses (GRPs) are sporadic bursts emitted by some pulsars that last a few microseconds and are hundreds to thousands of times brighter than regular pulses from these sources. The only GRP-associated emission outside of radio wavelengths is from the Crab Pulsar, where optical emission is enhanced by a few percentage points during GRPs. We observed the Crab Pulsar simultaneously at x-ray and radio wavelengths, finding enhancement of the x-ray emission by 3.8 ± 0.7% (a 5.4σ detection) coinciding with GRPs. This implies that the total emitted energy from GRPs is tens to hundreds of times higher than previously known. We discuss the implications for the pulsar emission mechanism and extragalactic fast radio bursts.

    In this work, we have studied the signals of auroral kilometer radiation (AKR) from sources in the auroral regions of the Northern and Southern hemispheres simultaneously recorded by one satellite. We have carried out a detailed statistical analysis of more than 20 months of continuous AKR measurements made by the ERG satellite (also known as Arase). This made it possible to confirm the previously obtained results on the location of AKR sources and seasonal changes in the radiation intensity. Open questions about the processes in the AKR source can be solved using data on the radiation pattern under various geomagnetic conditions. To answer these questions, we have estimated the cone angle of directional diagrams in the dusk and dawn sectors of Earth’s magnetosphere.

    We have been performing ground-based observations of Jupiter's sodium nebula longer than two decades. The sodium atoms in the nebula originate in Io's volcanic gas. The nebula distributes over 1,000 Jupiter's radii, and its angular size is approximately 10 degrees. Therefore, ground-based observations of D-line emissions in the sodium nebula can be made with small optics. The observation results indicate that the sodium D-line brightness in the nebula varies with various timescales like day-to-day through year-to-year. While it is naturally expected that variations in the brightness of the nebula reflect that of volcanism on Io, it may be influenced by locations of active volcanic plumes on Io. Sometimes, variations of the nebula differ between the eastern and western sides of Jupiter. &amp;#160;Details on the variations of Jupiter's extended sodium nebula will be shown. Especially, a period in which Juno spacecraft has been orbiting Jupiter will be focused.&amp;#160;

    Volcanic gases, primarily composed of SO2, SO, and S, originating from Io are ionized through interactions with magnetospheric plasma, forming a dense plasma region known as the Io plasma torus. Ion pickup serves as the most significant energy source for the plasma torus though, the spatial distribution of the pickup region and its temporal variability remain poorly understood. Measuring ion distributions with sufficient spatial resolution enables the derivation of ion temperatures and temperature anisotropy, being closely related to the influx of fresh pickup ions.Since 2014, we have carried out ground-based observations of sulfur ion emissions ([SII] 671.6 nm and 673.1 nm) from the Io plasma torus at the Haleakal Observatory in Hawaii, utilizing Tohoku 60-cm telescope. The telescope is equipped with a monochromatic imager and a coronagraph, enabling us to observe the distribution of singly charged sulfur ions with a spatial resolution as fine as 0.03 Jovian radii. This unique setup has allowed us to track changes in the torus structure with high spatial and temporal precision.Over the past six years, our observations revealed five significant peaks in [SII] brightness. For three of these events, we observed that the [SII] ribbon scale height began to increase shortly after the brightness peaks. This phenomenon likely indicates a rise in ion temperature, driven by volcanic outbursts on Io that introduce fresh ions into the torus. Such findings provide critical insights into the dynamic nature of the Io plasma torus and its response to volcanic activity.In this presentation, we will review past and ongoing remote sensing projects, present the latest observational results from our multi-year campaign, and discuss future plans for supporting upcoming space missions.

    Remote sensing with ultraviolet wavelength (UV) are one of powerful probes to uncover dynamic behaviors of the planetary environment. The Hisaki satellite was an earth orbiting extreme ultraviolet (EUV) spectroscope dedicated for observing solar system planets. Thanks to its long-term monitoring capability, Hisaki had carried out unprecedented continuous observation of Io plasma torus, Jovian aurora, and Mars and Venus upper atmospheres from 2013 to 2023. One of notable phenomena observed by Hisaki is significant enhancements of neutral gas from presumed activation of volcanic activity on Io. Hisaki revealed, for the first time, that not only the plasma source, but transport, heating, and loss processes of magnetospheric plasma were influenced by the variation in the neutral source input.After the end of the Hisaki mission, we have proposed the next UV space telescope, LAPYUTA (Life-environmentology, Astronomy, and PlanetarY Ultraviolet Telescope Assembly). One of goals of this mission is dynamics of our solar system planets and moons as the most quantifiable archetypes of extraterrestrial habitable environments in the universe. LAPYUTA will not only provide a UV monitoring platform like Hisaki but also have a high spatial resolution and high sensitivity to uncover stability of Io&amp;#8217;s atmosphere, water plumes that gushes from the subsurface ocean of icy moons, and spatio-temporal aspects of Jupiter's giant UV aurora. Primary goal of the LAPYUTA mission other than the Jovian system includes atmospheric evolution of Venus and Mars, characterization of exoplanet atmosphere, galaxy formation, and time-domain astronomy.

    Hisaki is an earth orbiting extreme ultraviolet spectroscope dedicated for observing solar system planets. Thanks to its monitoring capability, Hisaki has carried out unprecedented continuous observation of Io plasma torus, Jovian aurora, and Mars and Venus upper atmosphere since December 2013. One of notable phenomena observed by Hisaki is significant enhancements of neutral gas (sodium and oxygen) from Io occurred in the spring of 2015. Hisaki revealed that not only the plasma source, but transport, heating, and loss processes of magnetospheric plasma were influenced by the variation in the neutral source input. The presentation will include related topics from recent Hisaki publication. Since the autumn of 2016, the Juno spacecraft was in the orbit around Jupiter. Hisaki monitored activities of Jovian aurora and the plasma torus in the Juno era. These datasets will provide opportunities to compare in-situ observation by Juno with the global view by Hisaki.&amp;#160;JAXA approved the Hisaki mission period by the end of March 2023. As a future remote observation platform, we are going to propose a UV space telescope, LAPYUTA (Life-environmentology, Astronomy, and PlanetarY Ultraviolet Telescope Assembly), a Japanese-leading mission using heritages of UV instruments for planetary science (e.g., Hisaki) and space telescope techniques for astronomy. One of goals of this mission is dynamics of our solar system planets and moons as the most quantifiable archetypes of extraterrestrial habitable environments in the universe. Water plume that gushes from the subsurface ocean of Galilean moons and tenuous atmosphere which is generated by bombardment of energetic charged particles to the surface are primary targets of LAPYUTA. As the plume activity and the atmosphere are not stable, continuous monitoring with high spatial resolution is essential. The icy moon's plume and ambient space will be deeply explored with the spacecraft by NASA's and ESA's icy moon missions in 2020s-2030s. The complementary remote sensing by LAPYUTA will visualize their global structure and temporal dynamics.

    放射線帯外帯の相対論的電子は、磁気圏内で発生するプラズマ波動との相互作用により散乱され地球大気に降下する。この過程は、磁気嵐の主相における外帯消失の要因の一つと考えられており、降下した相対論的電子は、国際宇宙ステーションや低軌道衛星への悪影響、下部電離圏での電子密度増加に伴う通信障害を引き起こし得る。本研究では、放射線帯の相対論的電子を降下消失させる電磁イオンサイクロトロン（EMIC）波動に着目した。電子降下は、VLF/LF帯の人工電波を用いて観測した。地上と電離圏下端の間を長距離伝搬する電波の信号は、電子降下に伴う電離圏D領域高度での局所的な擾乱により振幅・位相変調をうける。本研究では、複合地上観測により、2017年3月27日の磁気嵐主相時のEMIC波動とそれに伴う相対論的電子降下の時空間対応を調べた。その結果、数10秒から数分の時間スケールで変化するEMIC波動強度の増大時に、相対論的電子が散乱され大気に降下消失することが明らかとなった。

    Serious problems of leakage field by indoor PLC have been pointed out previously by many authors. Nevertheless, the use of PLC in outdoor is recently discussed by MIC. In order to emphasize the risk of PLC, we measured the intensity of leaked emissions by indoor PLC in a case of Japanese wooden house near the downtown in Echizen-city, Fukui prefecture of Japan. The results show strong leaked emissions whose power significantly exceeds a technical criterion established by Radio Regulatory Council are radiated by indoor PLC in a case of usual Japanese wooden house.

    太陽系最大の磁気圏を持つ木星には,数十MeVに達する相対論的電子や数百MeVにおよぶイオンによって構成される放射線帯が存在する.木星放射線帯は従来,磁気圏内を高エネルギー粒子が木星近傍の放射線帯領域まで輸送されることによる供給過程と,その過程で生じる衛星やリングとの衝突等による消失過程とのバランスにより形成されると考えられてきた.その一方で近年,木星内部磁気圏で発生するプラズマ波動であるホイッスラーモード・コーラス放射と,高エネルギー電子との相互作用が,放射線帯形成過程において果たす役割の重要性が注目されつつある.その契機となったのは,地球放射線帯の形成過程に関する研究の展開であった.木星及び地球放射線帯研究の密接な関連を示す最近の研究成果を紹介し,特に衛星IoからGanymede公転軌道の領域を探査することの重要性について述べる.

    There have been the concerns that the Japanese broadband Power Line Communications (PLC) may cause harmful interference to a variety of radio services. It is thought that the interference would be maximal for the radio astronomy observations where extremely weak signals are observed by very sensitive receiving systems. We carried out measurements of the leaked emissions caused by PLC modems by using HF radio astronomy antennas that are actually used. The measurements were conducted at the litate observatory of the Tohoku university, and it was found that the leaked emissions from the house were detected even at the distance of about 130m, and that the intensities are stronger than the threshold levels of interference harmful to the radio astronomy observations by more than a factor of about 50,000. This result would indicate that the radio astronomy observations in the HF band could be strongly disturbed by the PLC modems.

    Measurements on the leaked electric field, when the in-house broadband power line communication (PLC) devices are in use, have so far been made with the separation distance not exceeding 10m. We measured the field strength farther than 10m, that has not been known, and found cases that the field strength exceeds the ambient noise by more than 20dB at the separation distance of 30m. We also made "direct" measurements on the common mode current (CMI) "on" the in-house power line, that has been regarded as the source of the leaked field, and found cases that the CMI exceeds the CMI limit for the Japanese PLC devices by more than 20dB.

    The Magnetospheric Imaging Instrument (MIMI) onboard the Cassini spacecraft has observed energetic particles in Saturn&#039;s magnetosphere. In order to clarify energetic particle distribution, we have investigated pitch angle distributions of 20 keV – a few MeV electrons in the inner magnetosphere (&lt;15 Rs). In this presentation, we will discuss the effect of absorption by the E-ring and the possibility of wave-particle interactions based on the Radio and Plasma Wave Science (RPWS) data.

    本年度の繰り越し分の経費を用いて，イオ火山の活発化に伴うイオプラズマトーラスの高温電子輸送のパラメタ特定，とくに朝夕非対称性について議論を深めることができた． 具体的には，ひさき衛星のデータの中から，５つのイオ火山イベントに関連するデータを抽出し，それらに対してスペクトルフィッティング手法を通してプラズマの密度および温度を導出する手法を確立した．これまでは，頻度の低い高分解モードでのスペクトルにしか適応できなかったこのパラメタ導出を，広視野（低分解能）モードのデータにも適用可能になる手法を確立したことにより，プラズマパラメタの導出を時間軸に拡張することに成功した． NASAのJuno探査機の研究チームのその場観測データと，米国コロラド大学の研究チームが開発しているモデルを組み合わせることで，ひさき衛星のデータから導出したパラメタとの整合性を確認できた．ただし，NASA/Juno探査機の高エネルギー電子やイオン観測装置などによる，木星内部磁気圏のその場観測データの解析に関しては，当初想定していたほどの進捗は見られなかった．これは主にCOVID-19による海外渡航の制限が主な原因であるが，今後は遠隔体制でも効率よくデータ解析できるシステムを構築する．また，小研究会の開催などを通して引き続き米国の研究チームと密に連絡を取り合うことで，校正データの共有などを高頻度で進める．なお，今年度の研究成果として国際学術論文誌２編と博士論文１件，修士論文４件が発表された．

    For demonstration of bistatic radar observation of the asteroids by the experiments with scale-down media model, development of linear chirp radar operated in a frequency range of 0.1-1.3 GHz, experiments using scale-down media model (diameter: 0.6 m. including sands, voids, and rocks), and inversion analysis have been performed. Not only the way in which transmitter and receiver were separately installed on two orbiters but also another way in which radar installed on one orbiter and reflector installed on other orbiter were demonstrated. Changing relative locations among the media model, transmitting antenna, receiving antenna, and reflector, the intensity and delay time of echoes scattered within the media model were measured by the radar. By applying Kirchhoff migration to measured data, we could obtain good inversion images of the internal structure of the media model.

    We have studied Jupiter, which has a strong magnetic field similar to the Earth. There is also a region called the magnetosphere around Jupiter, inside which Jupiter's moon (Io satellite) orbits. The satellite Io has volcanic activity, and gas emitted from the volcano becomes ions, forming a torus like Saturn's ring. Then, due to the influence of this volcano, the rotation cycle of Jupiter changes, and the electrons carried from the area far away from Jupiter (area 10-30 times the radius of Jupiter away from Jupiter toward anti-sunward). Since the last century researchers had doubted the truth and existence. Our results were derived by comprehensively analyzing the observation data of satellites made in Japan (Hisaki) and the United States(Juno).

    It is known from ground based observations of their synchrotron radiations that there are quasi-periodic 'extremely short term variations (hereafter ESTV)' of high energy electrons in Jupiter's radiation, whose intensity change is up to several-ten percent within one day and periodicity is generally a few to several days. This study has been performed to reveal unknown processes of ESTV based on observations of Jupiter's synchrotron radiation and analyses of scientific satellite and spacecraft data. As the result, it is shown that ESTV well correlate with magnetic reconnection events occur in Jupiter's outer magnetosphere. This fact suggests that global reconfiguration of Jupiter's magnetosphere affect deep inner region and rapid increase of high energy electrons.

    Toward the understanding of physical status of neutron stars, we conducted pulsar observations with multiple radio telescopes available in Japan, and succeeded in discovery of giant radio pulses (GRP) of the Crab pulsar which had wide frequency coverages from 300MHz to 8GHz, as well as detection of a few % X-ray pulse intensity increases concurrent with GRP. In addition, we succeeded follow-up observations of the Crab pulsar's lagest-ever glitch (a rapid jump in rotation frequency|) and an outburst of XTEJ1810-197, a neutron star having ultra-strong magnetic field, both of which occurred during the term of this research budget.

    The innermost Galilean satellite, Io, supplies a large amount of volcanic gases to the Jovian magnetosphere, and the outward transport of ionized gasses is responsible for forming a huge and rotation-dominant magnetosphere. The plasma supply from the satellite has a key role in the characterization of the Jovian magnetosphere. Using a continuous data set of the Io plasma torus obtained from an extreme ultraviolet spectroscope onboard the HISAKI satellit, it is found that the volcanic eruptions in Io caused significant variations of the plasma population in the inner magnetosphere. Intense short-lived auroral brightenings which represent transient energy releases in the outer part of the magnetosphere occurred frequently during this period. This is the first observational evidence showing that the strength of a plasma source in the inner magnetosphere can control a large-scale radial circulation of mass and energy in a rotation-dominant magnetosphere.

    The purpose of this study is to clarify the atmosphere-magnetosphere coupling in Jupiter using continuous monitoring data of planetary atmosphere and plasma phenomena obtained with our observation facilities at the summit of Haleakala, Hawaii (altitude 3000 m). In the summer of 2014, the Tohoku University 60 cm telescope was relocated to Haleakala, and we started continuous observation of Io’s sulfur ion torus emission at 673 nm with a visible high-resolution spectrograph. Furthermore, we carried out simultaneous observation of Io’s torus emission and Jupiter’s aurora in the ultra-violet range with a planetary space telescope Hisaki/EXCEED, and examined the causal relationship between the Io torus dynamics and the Jupiter auroral activity associated with the activation of Io’s volcano particularly for the events occurred in January 2015. In addition, we performed the precise observation of Jupiter infrared aurora using the Subaru telescope and NASA/IRTF every year.

    We investigated the lower ionospheric properties based on the magnetic amplitude from the world wide VLF/LF transmitters in Antarctica. Seven transmitter stations were identified from short-term observations on West Ongul Island, which has little electromagnetic interference. During this project, we developed the VLF/LF observation system consisting of orthogonal cross loop, pre- and main amplifiers, A/D signal processing unit, recording unit and observation software. The developed observation system was installed in Syowa base, Antarctica after test observations in Japan. In Syowa base, we successfully identified the two stations and derived the diurnal pattern of the magnetic amplitude during continuous observation over two years despite strong electromagnetic interference. In the future, we will continue analyzing our precious long-term data and study the lower ionospheric response from parameters related to global lightning activity, space weather.

    During 2013-2015 physical years, we could install new VLF observation system in Philippines and Vietnam to reveal the effects of lightning discharges on the lower ionosphere. All the five observation stations of Asia VLF Observation Network (AVON) were completed. By analyzing the AVON data, the following results were obtained. (1) The phase change strongly depends in both strength of EMP and distance of causative lightning from the 1-hop point, if the strength of the EMP exceeds the breakdown electric field at 90 km altitude. (2) Outside of these distances, the phase decreases (which correspond to the ionization decrease) was found. Intensity of EMP degreases as distance from a causative lightning. When the electric filed strength becomes lower than the breakdown threshold, electron attachment rate dominates ionization rate, causing decrease in ionization. This suggests that EMP does not affect ionization state in the lower ionosphere just above lightning.

For this purpose, the horizontal distributions of sprites and the electrical properties of the sprite-producing lightning discharges are studied using the data obtained by the JEM-GLIMS measurements at the ISS and using ground-based lightning data. First, we established the analytical method to identify weak sprite emissions from the incomparably intense lightning emissions in the JEM-GLIMS data. Based on the detailed data analyses of the 42 sprite events identified by that method, the spatial distributions of sprites and the horizontal displacement of the sprites from the sprite-producing lightning discharges are quantitatively identified. From the detailed comparison between the sprite distributions and source locations of the VHF pulses excited by the sprite-producing lightning currents, which is the first result in the world, the occurrence conditions of the sprites are clarified.

    Man-made VLF/LF radio wave observations have been started at Ny-Alsound in Norway and Athabasca in Canada. These observations have been used to study precipitations of high-energy (>100keV) electrons into the atmosphere during the geomagnetic storm and substorm. Local time distribution of the electron precipitation events was examined and was compared with the substorm onset timing. The data indicates that plasma wave are responsible for the energetic electron precipitation into the atmosphere through the pitch angle scattering.

    In order to investigate origin of unknown Mercury's exospheric atmosphere, ground-based optical observations have been made for Mercury's sodium atmosphere with high spatial resolution at optimum observations sites, the island of Maui, Hawaii and Alice Springs, Australia. Generation processes of Mercury's exospheric atmosphere have been examined by comparing the observation results with modeled atmospheres which have been calculated using the numerical simulation code originally developed by Tohoku University.

    We performed the development of a high-resolution spectrometer for observing Jupiter's infrared auroral intensity and it's Doppler shift in order to clarify the Jupiter's polar ionospheric dynamics. First we carried out detailed discussion on the characteristics of the scientific targets and accordingly, achieved the optical designing to measure Jupiter's aurora. We adopted an Echelle grating for this high-resolution spectrometer. Next we designed and fabricated some important elements of this instrument, such as the Echelle grating holder, the slit viewer and slit unit. However, on the third year in 2010 we discussed the budget allocation in detail, and found considerable shortage of the budget. Therefore, it is necessary to carry out the re-designing of optical system drastically to reduce the cost. Using the instrument with new optical design, we still achieve the scientific subjects of Jupiter's aurora. Mainly due to the re-designing review process, we could not complete the development of instrument during this research period. However, the development will be finised within two years.

    In order to investigate TLEs, TGFs, global lightning activities, and their effects on the atmosphere/ionosphere/magnetosphere, university microsatellite, named SPRITE-SAT (RISING) was developed successfully and launched in January 2009. Ground-based lightning observation networks using ELF and VLF radio wave were also developed and operated. Based on the data obtained by the ground-based instruments and previously launched satellites, various kinds of data analysis have been carried out, which contribute to the understanding of basic mechanisms of TLEs/TGFs, global lightning activity and their quantitative effects.

    The radiation mechanism of the Jupiter's decametric radio emissions has not been fully understood. We developed a Jupiter radio e-VLBI system over the Internet. We successfully received Jupiter radio emissions by using this e-VLBI system. The micro structures of Jupiter radio source are also considered by the model of Jupiter radio searchlight beam. This study is very important step toward the moon-earth baseline VLBI to investigate the Jupiter radio source in detail.

    The main purposes of this study are the followings: 1) How the gases originated from Jupiter's satellite Io, which are considered to be main plasma source of Jupiter's magnetosphere, are generated and released from Io, 2) how the Iogenic plasma is accelerated to nearly corotation speed, and 3) how the Iogenic plasma is thermalized from the cold state just after the gas is generated to the hot state as known from ground based observations and planetary explorers. In order to investigate them, regular optical observations for the Iogenic gas and plasma had been carried out about one month a year at Mt. Haleakara, Maui, Hawaii which is one of the best optical observation sites in the world. And, numerical simulations had been made for the three scientific subjects, respectively. 1. Results of the observations: 1) These is always an east-west asymmetry of the Iogenic sodium gas which is distributed beyond several tens Jovian radii (sodium nebula). 2) The plasma speed near Io's orbit is always slower than the corotation speed, and the speed shows magnetic longitude dependence and dawn-dusk asymmetry. 3) Plasma temperatures near Io's orbit is derived for the parallel and perpendicular directions with respect to Jupiter's local magnetic field. 2. Results of the numerical simulations: 1) The dominant release process of the Iogenic gas (sodium nebula) would be dissociation or dissociative recombination of the Iogenic plasma, and the amount of the released gas would be largest/smallest when Io is in the dawn/dusk sides. 2) A current circuit would be made between the plasma near the Io orbit and Jupiter's ionosphere which has longitudinal asymmetry in the conductivity due to the local time dependence of the solar UV irradiation, and quasi-uniform longitudinal currents would make the observed accelerated plasma flow which is slower than the corotation speed with the dawn-dusk asymmetry. 3) Iion-cyclotron waves would be generated in the just ionized Iogenic plasma due to a plasma instability induced by the "ring distribution", and the waves might make the observed thermal conditions by thermalizing the plasma through the wave-particle interaction (pitch angel scattering).

    1. Development of a 2D spectro-imaging system for exospheric atmospheres A spectro-imaging system for detection of sodium emissions of exospheric atmospheres of planets and satellites is developed. The system consists of 1)a dimension converting optics made of an optical fiber bundle, and 2)a F-number adjusting optics to connect the dimension converting optics to light-entrance and exit optics. The optical fiber bundle is arranged in 12x12(entrance) and 144x1(exit). The system is set up on an optical bench and connected to the 60cm diameter coude telescope (entrance side) and high-resolution grating spectrometer (exit side) of Tohoku University. A spectrum datum is projected onto a Li-N2 cooled CCD camera and reconstructed to a spectro-image on a computer. 2. Observations of exospheric atmospheres of Io and Mercury Observations of exospheric atmospheres of Io, one of the Galilean satellites, and Mercury have been made using the spectro-imaging system. It has been suggested that production rate of Io's atmosphere depends on Io's phase angel (Io's apparent position with respect to Jupiter). In order to confirm the dependence, we have made observations of Io for various Io's phase angles and obtained significant data-sets. On the other hand, Mercury observations have been made intensively for the period when Mercury is viewed largely apart from the sun. Due to bad weather condition in main, reliable images for investigating gas production processes have not been sufficiently acquired in the research period. We plan to make follow-up observations after June, 2006 when Mercury is viewed most largely apart from the sun in 2006. 3. Numerical simulation for investigating gas production processes A Monte-Carlo simulation model has been developed and adopted for the investigations of gas production processes. As the result for Mercury's atmosphere, it is suggested that ion sputtering by solar wind protons is operated further more effectively than previously predicted on Mercury's surface to product the atmosphere. As for Io's atmosphere, it is inferred that the amount of the atmosphere might be controlled by the coupling process of sputtering and/or peering by Jupiter's magnetospheric plasma and the photon stimulated desorption by the sunlight.

    Optical observations in this research were carried out at Haleakal High Altitude Observatory annually in February and March every year when Jupiter was close to its opposition. Observation of sulfur ion emission in the Io plasma torus was preliminary tried using a combination of 28cm Schmidt-Cassegrain telescope and a cooled CCD camera equipped with an interference filter in fiscal year of 2002. In fiscal year of 2003, observation was carried out using a newly developed Fabry-Perot imager with wavelength resolving power of 60,000, which was connected to a 35cm Schmidt-Cassegrain telescope. Same observation was continued also in fiscal year of 2004. By using a Fabry-Perot imager, it became possible to make Doppler resolved observation. This allowed us to obtain 2-dimensional distributions of intensity of sulfur ion emission, bulk velocity of sulfur ions in the plasma torus and its deviation from corotation of Jovian magnetic field, and ion temperatures both parallel and perpendicular to the magnetic field line. As for sodium emission, observations of sodium nebula extending by 400 Jovian radii from Jupiter were carried out using a wide field imaging instrument with a field of view of 5.7 degree in each year. In addition to these observations, in fiscal year of 2004, observation of distribution of sodium emission in close proximity of lo was made using a Fabry-Perot imager coupled to a 3.7m AEOS telescope equipped with an adaptive optics system. This observation allowed us to obtain asymmetric distribution of sodium atoms close to Io.

    1) Development of the 2D imaging system for Mercury's atmospheric The 2D imaging system for detection of the atmospheric weak emission layer surrounding Mercury is successfully developed based on the corona-graph technique. The observation wave length is set at the emissions of Na-D lines. The contrast between a weak emission surrounding a bright emission region (observation object) and the bright region is achieved to be 1:1000. 2) Observations of Mercury's atmosphere: current status The observations were made for Dec. 2001 and April 2002. Due to a hard atmospheric smearing effect caused by a seasonal wind and low altitude of Mercury, reliable images have not been acquired successfully for the periods. However, we could establish observation and analysis methods which are required to derive 2D image of the weak emission layer of Mercury's atmosphere. 3) Monte-Carlo simulation analysis for Mercury's atmosphere A Monte-Carlo simulation analysis for neutral and ionized particles has been made to investigate generation processes of Mercury's extended atmosphere, which is observed as the weak emission layer. As the result, it is suggested that plausible processes of the extended atmosphere are ion-sputtering or/and meteoritic vaporization, and the quantitative 2D imaging for the weak emission layer is quite important to determine the proper gas release process.

    To study the acceleration and dynamics of energetic particles in the Jovian magnetosphere, the development of the observation system for Jovian synchrotron radiation was performed. (1) After the improvement and adjustment of the observation system, the performance experiments was carried out. And the system has been established. (2) The software for the automatic operation, including the phase and gain calibration was successfully completed, which are essential to detect the absolute intensity of the Jovian synchrotron radiation for a long term. (3) The simultaneous observations of the Jovian synchrotron radiation at Kiso and Fuji observatories, Nagoya University, using the 327 MHz radio telescopes were carried out, and detected the daily variation of the radiation. (4) From the analyzes of the energetic particle data provided from NASA database, the response of the Jovian magnetopause for the solar wind variation and particle boundary in the Jovian magnetosphere were derived. (5) The data analyzes of the Ulysses spacecraft, the periodic modulation of Jovian energetic electrons with the period of about 40 min was discovered in interplanetary space (6) The dynamics of the earth's radiation belts was studied as the counter part of the Jovian radiation belt. From the detailed investigation of energetic electrons, unexpected pitch angle distributions in the equatorial region in the inner magnetosphere were discovered, which is strongly related to the intense plasma waves called EPWAT (equatorial plasma wave turbulence). (7) The dynamics of the outer radiation belt associated with magnetic storms was studied, and proposed the mechanism to accelerate hot electrons to relativistic energies through the interaction with the storm time whistler mode waves.

    The study, 2-dimensional imaging observations of the D-line emission distribution of logenic sodium atoms, which is regarded as a tracer of logenic volcanic gases, were performed with two field of views (FOV), namely±20Rj (narrow FOV ; Rj : Jovian radius), and ±400Rj (wide FOV). From the observational results, the following characteristics of emission distribution were obtained. In the narrow FOV observation, two different types of distribution extending to〜20Rj, that is, the band-shaped distribution and the spray-shaped distribution, were observed simultaneously. In the wide FOV observation, the elongated oval-like emission distribution extended to as much as 400Rj along the equatorial plane was observed. The east-west intensity asymmetry was also observed, with a dependence on the Io phase angle. Based on the observed images , we then made model analyses to investigate supply processes of sodium atoms and time variation of sodium distribution, and presented the comprehensive source process which can consistently reproduce the observed characteristics both in the narrow and wide FOV observation. From the model analysis for the narrow FOV observational results, it is concluded that the band-shaped distribution is attributed to the molecular ion destruction process, and the typical gyrovelocity of the molecular ions is estimated to be 20km/sec. It is also concluded that the spray-shaped distribution is produced through the charge exchange process. Then a combination of the two processes was examined for the wide FOV observational results. The combined model analysis could fairly reproduce the observed features of the wide extended sodium distribution. In the course of the model analysis, some important physical processes and related parameters are suggested.
