The Shock-ICME Complex Structure observed by Wind and Venus Express
Abstract
During 2012 June 13-15, STEREO/SECCHI coronagraphs recorded two successive launched Earth-directed coronal mass ejections (CMEs). At that time the separations between Venus and Earth is below 10° in heliocentric longitude. Two interacted interplanetary coronal mass ejections (ICMEs) can be observed by the WIND and Venus Express spacecraft, which provided a valuable opportunity to observe the process of the CME overtaken by a following fast ejecta and the ejecta-driven shock, and its enhancement of ICME's geoeffectiveness.
