It extended over half the diameter of the Sun - about 50 million

February 2003, though apparently the two did not interact. These
erupting prominences have been identified as the source of many CMEs,
though the physical process that triggers their eruptions has not yet
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 email@example.com.
