Pick of The Week
 
 

Double Trouble (May 9, 2002)

  • Two coronal mass ejections (CMEs) were captured by SOHO's LASCO C2 instrument on 2 May 2002. Nearly simultaneously, two CMEs blasted into opposite directions (at the two o'clock and eight o'clock positions) from the Sun, a fairly uncommon occurrence. CMEs eject a billion tons of particles traveling millions of miles an hour. The dark disk blocks the Sun so that the LASCO instrument can observe the structures of the corona in visible light. Neither of these events seemed to have triggered any aurora activity on Earth.

    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.
