Dynamics and characteristics of electric-field structures in the auroral return current region observed by Cluster

André, M.; Buchert, S.; Kistler, L. M. +5 more

The temporal evolution and other characteristics of intense quasi-static electric fields in the return current region are discussed using Cluster observations. A narrow-scale, divergent electric field, the high-altitude signature of a positive U-shaped potential structure, was observed at the poleward edge of the central plasma sheet, close to mag…
