A CME Roars Away (December 17, 2001)

  • Higher resolution version (TIF,3.3M)
  • These three images taken in less than an hour by the LASCO C2 instrument on Dec. 14, 2001 show a very rapidly expanding coronal mass ejection (CME) blasting billions of tons of particles out from the Sun at about four million kilometers per hour. The Sun, blocked by an occulting disk, is represented by the white circle. The breadth of view of the instrument is twelve solar radii or about 8.6 million kilometers. This event did not seem to be directed towards Earth.
