Accelerated electrons in Mercury’s magnetosphere observed during the 3rd Mercury flyby of BepiColombo

BepiColombo, launched in October 2018, is currently en route to Mercury. Although its planned orbit insertion is set for November 2026, BepiColombo continuously gathers new measurements during Mercury flybys. Throughout the cruise phase, the two spacecraft remain docked, with Mio protected behind the MOSIF sun shield, resulting in a limited observation for many instruments. Despite of such constraints, thanks to the smaller Larmor radii of electrons, wider range of electrons (from a few eV to a few hundreds of keV) got detected during the 3^rd Mercury flyby by Mercury Electron Analyzer (MEA) onboard Mio and Solar Intensity X-ray and Particle Spectrometer (SIXS) onboard the Mercury Planetary Orbiter (MPO). Both instruments show quite similar variations indicating that they are observing same populations of electrons with wider energy range, and small differences in time indicate there are time-of-flight of electrons related to the drift motion of particles in the magnetosphere. Together with Plasma Wave Investigations (PWI) onboard Mio, the possible electron accelerations and transport will be discussed.
