• CME heights (with respect to the disk center) are measured at the fastest segment of the leading edge.
  • PA= Position Angle measured from Solar North in degrees (counter-clockwise)
  • Halo CMEs are indicated in the "Central PA" column. The letters ("S", "BA", "OA") in the brackets show type of halo CMEs. See examples.
  • Click on date to view Java script movie of the CME.
  • Click on time to see height-time measurements as a text file.
  • Click on speed to view height-time plots of the CME.
  • Beware of data gaps. Check for LASCO/C2 data gaps here.
