Dawn/Dusk Dropouts due to Storms/Sub storms Near the Outer Radiation Belt: Observations from CRRES

Abstract

We investigate the particle dropout events from the dawn flank of the magnetosphere as observed from a variety of instruments on board the CRRES satellite. All dropouts are observed at magnetic latitudes more than 100 above the magnetic equator. Plasma and energetic electron and ion data help us establish the boundary regimes being sampled. During these events, the magnetic field shows a dramatic change in the field line configuration from a dipole-like to a highly stretched tail-like. The LLBL moved to geosynchronous altitudes, and at times, the magnetospheric lobe is sampled. We conclude that they are associated with substorm growth phase stretching of the geomagnetic field during periods of intense storm activity.
