Two CMEs (coronal mass ejections) expanded side-by-side into space in less than a day (July 1-2, 2013). The first and smaller of the two slowly emerged directly above the Sun. The second and much larger, faster event, which was apparently triggered by a filament eruption, blossomed out to the left. Neither one was expected to have any impact on Earth. In these coronagraphs, a disk covers the Sun, which is represented by the white circle.

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.
