Back-sided CME event (March 25, 2011)
Hi-res TIF image (2.6M)
The STEREO (Ahead) spacecraft caught this bright, substantial coronal mass ejection blast that emerged from the far side of the Sun, out of direct view from Earth (Mar. 21, 2011). Because it was from the far side (from Earth perspective), none of the ejected particle cloud was headed towards Earth. When that active region rotates around again, we?ll see if its potential power for generating solar storms remains as strong.
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.
