AB: During recent superstorms, observations from IMAGE, Iridium, FAST, DMSP, TIMED, LANL Geo and ground-based photometers at vantage points throughout the geospace system are used to investigate, for the first time, features that map from the inner magnetosphere to strong red emissions at mid-latitudes, reaching as far equatorward as 33 deg MLAT. At the lowest latitudes, emissions have very little structure being described as a diffuse but intense red glow. The observations imply that these visible unstructured mid-latitude emissions are in fact extreme stable auroral red (SAR) arcs, and that large-scale coupling processes, within the inner magnetosphere are key to producing an enhanced energy source to drive SAR-arc intensities into the visible range. This presentation will focus on the 31 March 2001 and 11 April 2001 extreme events but draw upon a larger set of storms for supporting observations. New questions raised by these observations, as well as initial modeling results, will be presented.
