Near-Earth Interplanetary Coronal Mass Ejections During Solar Cycle 23 (1996-aEuroparts per thousand2009): Catalog and Summary of Properties

In a previous study (Cane and Richardson, J. Geophys. Res. 108(A4), SSH6-1, 2003), we investigated the occurrence of interplanetary coronal mass ejections in the near-Earth solar wind during 1996 -aEuro parts per thousand 2002, corresponding to the increasing and maximum phases of solar cycle 23, and provided a comprehensive catalog of these events. In this paper, we present a revised and updated catalog of the a parts per thousand 300 near-Earth ICMEs in 1996 -aEuro parts per thousand 2009, encompassing the complete cycle 23, and summarize their basic properties and geomagnetic effects. In particular, solar wind composition and charge state observations are now considered when identifying the ICMEs. In general, these additional data confirm the earlier identifications based predominantly on other solar wind plasma and magnetic field parameters. However, the boundaries of ICME-like plasma based on charge state/composition data may deviate significantly from those based on conventional plasma/magnetic field parameters. Furthermore, the much studied magnetic clouds, with flux-rope-like magnetic field configurations, may form just a substructure of the total ICME interval.
