On June 23th at 09:44:21 UT BepiColombo performed the second flyby at Mercury. The trajectory was similar to the one of the first flyby, approaching from the night time (and magnetic tail) and exiting from the dayside, and with a closest approach of 198 km altitude, and about 18 minutes of eclipse. Both MIPA and PICAM sensors operated successfully during the whole flyby, between CA-24h and CA+48h with multiple programmed switch off during this window due to the wheel off loading procedure. MIPA operated in mode 11 during all the period and PICAM operated in two different modes to cover a wider range of energies (from 15 up to 1500 eV). According to preliminary analysis by the magnetometer onboard Bepi, the magnetopause inbound crossing occurred at about 09:16 UT and outbound at 09:52 UT, and bow shock shortly after at about 10:01 UT. Both the MIPA and PICAM data shows confirmation of such crossings and identify different populations of ions. The detailed analysis and identification of the different features observed is now ongoing.
