Evolution of CMEs in the Heliosphere at Solar Minimum
Abstract
The STEREO mission permits CMEs to be observed all the way from the Sun through the inner heliosphere to beyond the orbit of the Earth, from a vantage point away from the Sun-Earth line. We combine remotely-sensed imaging and in-situ observations of CMEs from STEREO and other missions with modeling of selected events to better understand how CMEs evolve as they propagate out from the Sun into the heliosphere, and to study the relationship between CMEs observed in imaging instruments and ICMEs observed in-situ. We present preliminary results from analysis and modeling of a small number of well-observed CME events during the present solar minimum period. These include the event of April 26, 2008 and the Earth-directed event on December 12, 2008.
