Electron Belts



a) Data from the CRRES satellite at the time of the March 24, 1991 SSC. Top panel shows count rates as a function of time from four energetic electron channels measuring integral counts above a threshold energy indicated, and also over 10-50 MeV [Blake et al., 1992]. Middle and bottom panels show the measured electric field in a co-rotational frame and the magnetic field component with a model magnetic field subtracted, in GSE coordinates over the same time interval [Wygant et al., 1993]. b) Simulated results in the same format as (a) measured at a spatial location corresponding to the trajectory of the CRRES satellite, including the Aerospace detector responses in the top panel.
