Scientific paper

The multiple viewpoints of the STEREO spacecraft combined with innovative techniques involving heliospheric imagers (SMEI (2003), HI (2006)) have enabled the study of (interplanetary) coronal mass ejections (CMEs) from a perspective that is unique in our scientific history. Scientific revelations are emerging about CMEs, many of which had been speculated upon but until now never observed. We present results from a single such event observed in November 2007. This event was Earth-directed, and our 3-D reconstruction analysis combined with in situ observations reveal that the event is a combination of a CME with a corotating interaction region (CIR). We believe the merger of these two structures occurs very near the Earth, with the CME to the east (toward STEREO-B) and the CIR to the west (STEREO-A). We offer two possible suggestions for how this combined structure could arise: Either the CME passed through an existing CIR or the CIR was created by the launch of the CME. The latter suggestion has potentially revolutionary implications for CME evolution through the heliosphere.
