Solar Storming with Some Halos (February 14, 2014)

The Sun popped off several coronal mass ejections (CMEs) in a little over three days (Feb. 10-13, 2014). The last pair of these storms occurred in quick succession and appeared to be halo CMEs, in that the edge of the particle cloud expands around the Sun roughly in the shape of a circular halo. These storms were either heading in the general direction of Earth or in the opposite direction away from Earth. The composite images here combine the Sun in extreme UV light from SDO with the two visible light coronagraphs from SOHO.

SOHO began its Weekly Pick some time after sending a weekly image or video clip to the American Museum of Natural History (Rose Center) in New York City. There, the SOHO Weekly Pick is displayed with some annotations on a large plasma display.

If your institution would also like to receive the same Weekly Pick from us for display (usually in Photoshop or QuickTime format), please send your inquiry to steele.hill@gsfc.nasa.gov.
