Thar She Blows (July 22, 2011)

The Sun popped off no less than five coronal mass ejections over three-days (July 19-22, 2011). While none of them appeared very strong, they do suggest that the level of solar activity is increasing as we progress further into this solar cycle. Here we have combined the Sun in extreme UV from the Solar Dynamics Observatory (SDO) with the C2 coronagraph from SOHO. Most of these solar storms seem to have emerged from the farside of the Sun.
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 email@example.com.
