Pick of The Week

Flurry of Action (April 30, 2003)

  • Higher-resolution (TIF,1.9M) version.


  • MPEG large (2.2M) and small (832K) version.
  • C2 Quicktime large (2.6M) and small (1.0M) version.

  • Over a very active three days this last week, at least nine solar storms (either solar flares or coronal mass ejections) erupted on the Sun (April 25-27, 2003). The still image of three LASCO C2 coronagraph frames shows the first and strongest CME. In it the structures of the expanding cloud are unusually strong and clearly defined. This and most of the others appear to have originated on the front side of the Sun. EIT images of the Sun in extreme ultraviolet light show erupting filaments associated with storms in at least three instances. And over the course of the three days (as can be seen in the video clip), by best estimate eight other storms occur, quite a flurry of activity. None of these storms seemed to have much impact on Earth as they were not Earth-directed, however the Sun continues to be peppered with spots this week so more storms should be expected.

    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.
