AB: The morphology of the ring current during storm main phases is controlled by a variety of factors, including the solar wind driving and the pre-storm plasma sheet conditions. The ring current morphology in return is crucial for understanding further development in the inner magnetosphere (e.g., the ring current-plasamsphere overlap and its impact on the radiation belts). We present statistical results from ENA-derived equatorial plasma distributions for geomagnetic storms between 2000 and 2006. We discuss the penetration depth of the ring current and the position of the peak in response to possible controlling solar wind and magnetospheric factors.
