[PCG19-09] The first simultaneous observation of low energy ions and electrons at Mercury during the first BepiColombo flyby
キーワード:BepiColombo、Mercury's magnetosphere
The first Mercury flyby by BepiColombo was successfully made on 1st of October 2021 and this is the first time to have the simultaneous observation of low energy ions and electrons at Mercury. The data from Mercury Plasma Particle Experiment (MPPE) onboard Mio/BepiColombo shows (1) the compressed Mercury’s magnetosphere compared to the average of MESSENGER observations, (2) boundary motions around magnetopause crossings, (3) low-frequency waves in both dawn and dusk sides, and (4) high energy ions and electrons after the closest approach.
