Over a 14-hour period on 20 September 2003, two coronal mass ejections (CMEs) erupted, one almost right after the other in the same direction. The series of still images from the LASCO C2 coronagraph shows the second and larger of the solar storms as it blasts away from the Sun and rapidly expands over a 96-minute period. These storms typically propel a billion tons of matter at millions of miles per hour. The video clip shows both CMEs. The field of view of the instrument is about 8 million km across. Neither storm appeared to be Earth-directed.

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.
