Fig. 2: Trajectory of BepiColombo and SERENA observations during MFB1.
From: Inner southern magnetosphere observation of Mercury via SERENA ion sensors in BepiColombo mission

The trajectory of BepiColombo during the interval of interest in the XMSM-RMSM plane. a PICAM observations, b MIPA observations. The solid gray line represents the magnetopause surface, while the dashed gray line corresponds to the bow shock surface25,26. Red lines in a correspond to the operational time of PICAM, blue line in b corresponds to MIPA operation time. Time labels are shown progressively along the trajectory. Insets 1–4 in a show PICAM spectrograms for each specific time window, while the inset in b displays MIPA spectrograms. Color bars report ion counts in each specific time interval. BC position data are given in the Source Datas file.
