Yet another CME (April 1, 2004)


Hi-res TIF image (1.2M)

The Sun is not going quietly into its period of solar minimum yet. A bulbous coronal mass ejection (CME) with a dense center (seen as white) exploded out from the Sun on March 29, 2004. This series shows a cloud of particles heading to the edge of the field of view of the C2 coronagraph in just over two hours. 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 and generate aurora if conditions are right.

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.
