From: Near-Earth plasma sheet boundary dynamics during substorm dipolarization
Multispacecraft observations of dipolarization. Magnetic field component normalized to the current sheet (B Z ) observed in the night-side magnetosphere is plotted from the post-midnight to pre-midnight regions: a GOES 13, b Van Allen Probe-A, c GOES 14, d GOES 15, e MMS3, g Geotail, h Cluster 1, together with f a combined product of energy spectra of electrons from MMS1 and MMS3 and i auroral electrojet indices. Electron spectra for energy lower/higher than 25Â keV are plotted using MMS3 FPI/MMS1 EIS data. For VAA traversing B Z , the difference from the model magnetic field (T89) is plotted. The vertical line indicates 09:42 and 09:57 UT, which are the positive bay onset times
