Important notice about STEREO Behind
The Sun blasted out two coronal mass ejections (CMEs) in quick succession over a 12-hour period (Dec. 2, 2012). The events are presented here by three of STEREO's (Ahead) instruments composited together. The Sun itself (shown in orangish-red) is seen in extreme UV light; the inner corona (green) by the COR1 coronagraph; and the larger coronal area by the COR2 coronagraph. The CME particle clouds were directed away from Earth.
