We report on BepiColombo SIXS observations of energetic electron populations in the Mercury Magnetosphere. Whilst on the first flyby we observed no such populations, on both the second and third flybys we observed strong energetic particle signatures. We will compare these with the measurements made by Messenger ( Lawrence et al., Lindsay et al.) The data was consistent with two separate populations, characterised by different pulsation frequencies, observed on the nightside, and cutting out sharply at the magnetopause exit. These are interpreted in the context of the Lawrence et al. observations.
