The plot shows three panels that summarize the geosynchronous activity in relation to the Dst time profile. Each plot covers 10 days but the flux and Dst amplitude scales are variable.
The top panel shows 50-75 keV electrons for each of the LANL geosynchronous satellites. This plot is indicative of the extent of substorm injection activity. Substorm injections appear most intense when the observing satellite is near midnight. Each satellite passes midnight at a different universal time so the envelope from multiple satellites is more representative of the global substorm activity. Five energy channels covering 50-315 keV are available for each satellite in the keV Electron Plots.
The middle panel shows 1.8-3.5 MeV radiation belt electrons for each of the same LANL geosynchronous satellites. Geosynchronous orbit lies in the outer portion of the radiation belts. Typically there is a decrease (dropout) of MeV electrons during the main phase of a magnetic storm followed by a recovery or an enhancement of MeV electron fluxes during the storm recovery phase. Four energy channels covering 0.7-7.8 MeV are available for each satellite in the MeV Electron Plots.
The bottom panel shows the preliminary Dst index for the same time period.
