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.
