Electron fluxes (~60 to ~280 keV) at the geosynchronous orbit by the LANL satellites on March 17, 2015, between 15:00 and 20:00 UT. The six first panels refer each to one satellite (name on the left y-axis) and its measured electron fluxes (each colour is one energy channel). The last panel shows the IU and IL (IMAGE) index for the same period. The vertical dashed and solid black lines correspond to the time before the electrojet enhancement and at their maximum intensity respectively, see also vertical orange lines in Figure 3, left panel (1D equivalent currents) or the numbered right panels.
