Two Observed Consequences of Penetration Electric Fields
Abstract
The influence of penetration electric fields (PEF) on storm-time energetic particles in the inner magnetosphere and on the stability of plasma in the low-latitude ionosphere is widely recognized. We describe two consequences of PEFs, regularly observed during magnetic storms that indicate their persistence throughout the main phases. These are (l) the presence of equatorial plasma bubbles (EPB) across the evening local time section during main phases and their absence throughout recovery, and (2) detections of low-energy ion precipitation in the dawn sector equatorward of the auroral electron boundary.
