Sun hurled two bright CMEs into space, both non-Earthbound

New region 1611 rotated into view on the east limb and produced a moderate M1.7 flare at 02:23 UTC and a type II radio sweep shortly after, on November 8, 2012. Flare generated bright coronal mass ejection (CME) in eastward direction which means that it would not be geoeffective.

Bellow is the video by NASA’s Solar Dynamics Observatory showing the extreme UV flash caused by flare-generated CME.

Later in the day another  bright full-halo CME was observed on the farside.  STEREO imagery indicated that old Region 1598 could be the source.  Because this was a farsided event, it will have no impact on Earth. Watch the video by STEREO Ahead and STEREO Ahead COR2.

Two CMEs may impact Mars and several spacecraft. The video below shows an animation of the NASA/SWPC ENLIL computer model of the CME’s propagation through the solar system. CME forecast model estimated that the CMEs may impact both STEREO spacecrafts, Spitzer and Messenger, as well as Mars. CME clouds will miss our planet this time.

There was a brief period of active geomagnetic conditions at the end of  November 7. Planetary K index reached Kp=4. The cause of this activity is not clear at the moment but it seems that it is caused by a coronal hole high-speed stream.
