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.
