pre-SAGA Events

Sometimes it happens that the ratemeters are subjected to sudden increases when the satellite approaches the SAGA (fig. ). These events are not frequent and are thought to be caused by huge charged particles' concentrations in the vicinities of the SAGA: when the satellite enters this regions, that only occasionally show such high-energy particle densities, these outstanding increases in the ratemeters are recorded.
