Coronal mass ejections were popping out from the Sun at a pace of two per day on average (Apr. 18-23, 2013). We counted ten CMEs for the five days, but some of the eruptions were complex and difficult to differentiate from one another. Almost all of them blew particles out to the left, most of them probably originating from the same active region.

These were taken by the STEREO (Ahead) spacecraft?s coronagraph, in which the black disk blocks the Sun (represented by the white circle) so that we can observe the fainter features beyond it.


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.
