JpGU-AGU Virtual Meeting 2020
This year’s JpGU meeting was converted to online, and today (12 July 2020) was the opening day. http://www.jpgu.org/meeting_j2020v/
Otsubo has a first-author “iPoster” titled “GGOS Japan’s roles and activities as a GGOS Affiliate” and a few more as a coauthor.
例年（今年も）学部学生は無料で参加できますので，興味のある皆さんはぜひ．
Hayabusa2 Orbit Determination study published
A paper led by Keiko Yamamoto of National Astronomical Observatory is published on Earth, Planets and Space. The orbits of Hayabusa2 spacecraft and the GM of Ryugu are investigated. Otsubo is involved in the key part of orbit analysis.

VLBI Orbit Determination Simulation study published
A paper written by Grzegorz Klopotek of Chalmers University of Technology, Sweden, in collaboration with Otsubo, is published on Journal of Geodesy. This is a challenging research seeking a possibility of VLBI technique for precise orbit determination of Earth orbiting satellites.

“MEMBER” ページ更新
卒業生２名と，新加入３年生４名について，“MEMBER” ページを更新しました．大学の新学期開始は５月になりましたが，先日（９日）に遠隔配信ゼミ（オリエンテーション）と，遠隔飲み会を実施したところです．４年生の協力のおかげで，予想以上に意思疎通ができました．
レンタルサーバ引っ越し
当研究室のウェブサーバーは，2016年よりレンタルサーバ EX-CLOUD にて運用してきましたが，このたび ColorfulBox に引っ越しました．もし閲覧上問題がありましたらぜひお知らせください．
