The Sun produced two rather large coronal mass ejections (CMEs) in profile over a 16-hour period, June 3-4, 2004. Both appear to be from the same area that had just rotated out of view of SOHO. And both could be fairly described as spectacular events. These were taken by the C2 coronagraph in which the Sun is blocked out by an occulting disk so that the activity in the corona can be observed.

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.
