Abrégé

A method for monitoring precipitation of magnetospheric particles includes detecting charged magnetospheric particles by a particles detector, processing the detection data to associate a respective estimate or measurement of kinetic energy with the detected magnetospheric particles, obtaining a first count value NH associated with a relatively higher estimate or measurement of kinetic energy, obtaining a second count value NL associated with a relatively lower estimate or measurement of kinetic energy, detecting a relative variation of the second count value NL with respect to the first count value NH, determining that an impulsive event of precipitation of charged magnetospheric particles (MPP event) in the magnetosphere occurred, assigning to the MPP event geomagnetic longitude and time, defining one or more groups of MPP events occurred in a time range at a same geomagnetic longitude, and identifying a group of MPP events indicative of an activity of terrestrial origin.
