A Very Fast CME (December 11, 2001)

  • Higher resolution image (TIF,806K)
  • EIT (Quicktime,2.7M), smaller version (Quicktime,551K)
  • C3 (Quicktime,1.8M), smaller version (Quicktime,389K)
  • EIT (MPEG,368K)
  • C3 (MPEG, 63K)
  • A good-sized and fast coronal mass ejection (CME) exploded out from the Sun on Dec. 11, 2001 and roared away from the Sun at about 3 million miles per hour (5 million km/hour). It was first captured by the SOHO Extreme Ultraviolet Imaging Telescope (EIT) in 1.5 million degree plasma at 195 Ångstroms as a bright flash (easier to see in the video clip). Just three hours later, the image taken by the LASCO C3 instrument shows a broad and expanding cloud of particles in visible light that is already over 10 million miles away from the Sun.
