Serial CMEs (May 28, 2010)
Hi-res TIF image (851K)
The Sun unleashed a series of four coronal mass ejections CMEs just in two-days (May 22-24, 2010) as the STEREO Ahead spacecraft watched the action. While the Sun has not been very active over the last two years, it can still pack some punches when it decides to. In the coronagraph images, the Sun, blocked out by an occulting disk (seen as red), is represented by a white disk to show its relative size. CMEs are large solar storms that expel a billion tons of matter at a million miles per hour or more.
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 firstname.lastname@example.org.
