Outline of Annual Research Achievements

本事業で各観測点に設置されたVLFアンテナ、誘導磁力計、高感度全天カメラ、リオメータ、EMCCDカメラや、平成28年12月に打ち上げられたあらせ衛星、本事業で開発されているモデリングなどを通じ、平成30年度には58件の査読付き論文を出版することができた。代表的な成果として以下のような結果が挙げられる。
・オーロラ帯から低緯度に分離してくるSARアークという赤いオーロラを見出し、カナダのサブオーロラ帯での長期観測データから、その統計的な特徴を明らかにした。このSARアークは、日本で見られる低緯度オーロラの原因の一つと考えられる。
・極小期の太陽の太陽風に特徴的な構造であるCIRに到来に伴い、180度以上の広い経度で同時にPc1地磁気脈動が発生している例が報告された。この例は、極小期で放射線帯電子の消失に寄与するイオンサイクロトロン波動がグローバルに発生しうることを示す重要な成果である。
・このCIRの到来で発生した磁気嵐の主相で、放射線帯電子が急激に減少していることがあらせ衛星で観測された。同時に観測された地上のデータから、Pc1地磁気脈動＝イオンサイクロトロン波動がこの消失に寄与していることが示唆されている。
・あらせ衛星で観測された磁気圏ELF/VLF波動の明滅と、地上のEMCCDカメラで観測された脈動オーロラの一種であるフラッシュオーロラの明滅が一対一で対応している例を見出し、このELF/VLF波動がフラッシュオーロラを生成させていることを明らかにした。

Current Status of Research Progress

2: Research has progressed on the whole more than it was originally planned.

Reason

・フィンランド、アイスランド、カナダ、ロシア、アラスカ、日本などの既存の観測点の自動定常観測を維持・継続するとともに、ロシアのZhigansk観測点にカメラを設置し、自動定常観測を開始した。これにより、カナダのNain観測点以外のすべての予定していた観測点において、自動定常観測を開始することができた。また、Nain観測点もVLFアンテナ、カメラ、リオメータ、誘導磁力計の設置を終了し、キャンペーンベースで稼働させることができている。
・これらの観測で得られるデータをERGサイエンスセンターとIUGONETによるデータベースを利用してデータベース化して公開し、国内・海外との共同研究を促進することができた。
・平成29年3月に定常観測を開始した日本のERG（あらせ）衛星の軌道に合わせて、平成30年度の春・秋にもキャンペーン観測を行った。また、米国のVan Alllen Probe衛星、THEMIS衛星などの内部磁気圏衛星との同時観測データの解析を進めることができた。
・波動と粒子の相互作用を局所的およびグローバルに評価するモデリングの開発を継続し、これらの観測と比較することで、モデルの改良と粒子加速・消失の定量評価を行った。

Strategy for Future Research Activity

・カナダのNain観測点には、フィールド機器は設置できたが、電源が無いためにパソコンなどの記録計を設置して観測を開始することができていない。今後、記録計を設置するとともに、電源が得られない場合は発電機を活用してあらせ上空通過時などに観測を行ってデータを取得していく。
・本研究では8か所の観測点・5種類の機器から大量のデータを得ている。これらの観測データはすべて大容量ストレージに保管され、世界的に広く使われているCDFフォーマットに変換されて、ネットワークを介して世界の研究者に公開されている。昨年度に引き続き、新しく得られてくるデータも世界の研究者に公開し、データ利用の促進と成果の創出をはかっていく。
・本事業ではホームページ（http://www.isee.nagoya-u.ac.jp/dimr/PWING/）を立ち上げてデータの説明や進捗状況、データへのリンク先などを公開している。このホームページを引き続き運用し、情報発信をはかっていく。さらに、関連研究の国際ワークショップや国際シンポジウムを開催して、成果の創出をはかっていく。
・本研究の成果は、科学論文として発表していくだけでなく、さまざまな形で社会へ発信していくことが重要である。このために、出前授業や、大学院生・若手研究者向けの国際スクール、重要な成果のプレスリリースなどを実施していく。
