A highly structured coronal mass ejection (CME) with a dense center (seen as white) blasted out from the Sun on Feb. 15, 2004. This fast-moving cloud of particles moved out of the field of view of the C2 coronagraph in just a few hours, but the streaming of particles continued to pour material out into space for the rest of the day (see video clip). CMEs are solar storms that propel billions of tons of material at millions of miles per hour. They also carry magnetic field away from the Sun, which can interact with the Earth's magnetosphere if directed our way.

Previous Picks of the Week

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.
