A series of coronal mass ejections erupted in just a 24 hour period (Apr. 14-15, 2011) as STEREO's (Ahead) spacecraft caught the action. None of these blasts were headed towards Earth since their sources were from active regions on the side of the Sun away from Earth. With a view of the entire Sun between STEREO's twin spacecraft and Solar Dynamics Observatory, we don?t miss any activity anymore.

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.
