Observations of a Solar Energetic Particle Eventon March 28th 2022 by the BepiColombo Satellite

On March 28, 2022, a particle flux increase was recorded at very different energies bythe several particle instruments on board the BepiColombo (BC) spacecraft.Specifically, an increase in the low-energy ion flux was measured by theSERENA/PICAM instrument and one in both the proton (1.5 20.7 MeV) andelectron (>0.5 MeV) flux was detected by the BERM radiation monitor. Theseobservations are consistent with the occurrence of a Solar Energetic Particle (SEP)event.This study presents a comprehensive analysis of the observed SEP event, exploitingBC's unique vantage point to explore temporal, spatial, and energetic characteristics,as well as observations from other spacecraft in the inner heliosphere.In conjunction with BC's observations, we used data from the STEREO-A, which isvery well magnetically connected with BC along the spiral magnetic field, and dataprovided by spacecraft positioned at the Lagrangian point L1, such as ACE andWIND, which are radially connected with BC. The findings provide insights into thephysical mechanisms governing SEP events, offering a perspective on their solarorigin, propagation, and evolution within the heliosphere.
