SOHO/LASCO CME Catalog

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.

*1 Acceleration is uncertain due to either poor height measurement or a small number of height-time measurements (See Section 3.4 of Yashiro et al. 2004 for details).
*2 Mass and Kinetic Energy are uncertain due to poor mass estimate. Mass measurement assumes that the CME material is in the sky-plane. Kinetic Energy is obtained from the mass and linear speed (see Vourlidas et al. 2000 for details).
