Abstract

We study-flow disturbances for selected substorm intervals when the aurora signatures obtained from Polar UV images could be followed from the initial brightening until the end of the recovery phase and when Geotail was located in the midtail region. We compare and contrast fast flows observations related to two different types of aurora: a small-scale poleward expanding bulge and an equatorward :extending N-S aurora (auroral streamer). The frontside flow shear of the fast flow is shown to be consistent with strong cross-tail localization of flow bursts within about 1 MLT of these auroral activation.
