| 概要 | 2024年5月に発生した宇宙嵐は、Dst<-400 nTに達する巨大なものであり、日本をはじめ世界各地でもオーロラが見えるなど大きな話題となりました。太陽、惑星間空間、磁気圏、電離圏、大気圏の太陽地球系システムの各観測、シミュレーションについての研究は、SGEPSSの多くのセッションに関わるため、セッション横断型の特別セッションとして提案します。この特別セッションにおいては、関連する観測やシミュレーション結果等の報告に加えて、例年レギュラーセッションに参加していない協賛会員や非会員から、この宇宙嵐に伴う社会影響などを含めた講演も広く募集することを計画したいと思います。なお、セッションでは、このイベントに限らず、第25活動周期に発生した他のイベントの講演も歓迎します。 |
