An overview of MagEIS electron flux measurements for the time interval under investigation. Six MagEIS energy channels are shown, ranging from 32 keV to 2.6 MeV, from the LOW (orange labels), M75 (blue labels), and HIGH units (red labels). Daily averaged solar wind speed (V SW) and D st data are shown for context. The daily averaged MagEIS fluxes have been corrected for background contamination, with the alternative correction algorithm (see text) used for L≤ 3 on the two highest energy channels shown (1.01 and 2.60 MeV). The long data gaps early in the time interval at L≥ 3 are due to the unavailability of MagEIS histogram data, which are required for the background corrections.
