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. 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. |
