Survey of Interplanetary Coronal Mass Ejections in the Near-Earth Solar Wind During 1996 -- 2005
Abstract
We extend and update our comprehensive survey of ICMEs in the near-Earth solar wind (Cane and Richardson, JGR, 2003) to include the declining phase of solar cycle 23, and take into account compositional signatures of ICMEs which help to refine the event identifications. We discuss the variation in properties such as occurrence rate (including evidence for a ~150-day periodicity), speed, magnetic field intensity, fraction of ICMEs that are magnetic clouds, the relationship between geomagnetic storms and ICME properties, and association between LASCO halo CMEs and near-Earth ICMEs. An updated list of ICMEs will also be presented.
