Abstract
We present a comprehensive catalog of geomagnetic storms (GSs) with a Dst index ≤−50 nT detected during solar cycles (SCs) 23 and 24 (1996–2019). About 550 events were identified in the Kyoto database and used as a starting point for this study. The solar origin of the GSs, in terms of coronal mass ejections (CMEs), solar flares (SFs), and in situ-observed energetic particles, was identified where possible using temporal constraints and wide Earth-directed ejecta. In addition, any accompanied interplanetary (IP) sources, such as ICMEs and IP shock waves detected at 1 AU, are also considered. The resulting occurrence rates and correlation plots are presented and discussed in the space weather framework.
