Using a quantitative identification of convection and particle boundaries at high latitudes, the relative extent of auroral convection and auroral precipitation is examined during superstorm events. During superstorms the convection reversal boundary normally located near 75° magnetic latitude moves to magnetic latitudes near 60°. The edge of the diffuse auroral precipitation that normally terminates near 60° magnetic latitude moves to magnetic latitudes near 40°. This limited study shows that during the main phase of the superstorm ion drifts driven by the magnetosphere penetrate to latitudes as low as the dip equator on the dusk side but extend only a few degrees equatorward of the auroral zone on the dawn side. Evidence for ion drifts driven by a disturbance dynamo may be found during the storm recovery phase when the interplanetary magnetic field is less strongly southward or turns northward, but the previously established flows below the auroral region remain.
