Abstract
Results are presented from a comparative analysis of geomagnetic events identified according to different indices. A way of identifying geomagnetic storms developed earlier using the Dst index is selected as the basis for identification. A similar technique for identifying geomagnetic events is obtained on the basis of the ap and AE indices. A comparative analysis includes identifying common geomagnetic events according to different indices; cases where an event is a strong geomagnetic disturbance according to one index (Dst, ap, or AE) but not a geomagnetic event by at least one of the two remaining indices; and considering the daily and seasonal distributions of geomagnetic events identified according to different indices.
