Twin CMEs? (December 7, 2007)
Hi-res TIF image (402K)
Over a five-day stretch (Nov. 30 - Dec. 4, 2007) SOHO observed two remarkably similar coronal mass ejections (CMEs). The first one blew out to the right from the Sun as a familiar arch- shaped, bulbous CME. Just four days later another, slightly larger, CME headed out to the right in just about the same direction and similarly shaped. With the Sun being near its minimum period of activity, it was a little surprising to see two CMEs in this short a span of time. With the brilliant Sun blocked out by the red occulting disk, we can tease out these features in the corona with our coronagraph instruments. The white circle represents the size of the Sun itself.
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.
