Subject: Partial halo CME on 2000/06/23

LASCO and EIT observed a partial halo CME on 2000/06/23. The event was
first observed in C2 at 14:54 UT, as abright loop front over the NW limb.
Fainter extensions could be seen later to the N and S of the main front.
The angular extent of the event was about 180 degrees, from PA 190 (S
pole) along the W limb to PA 10 (N pole). The plane-of-sky speed of the
leading edge was about 847 km/s at PA 300 (NW limb).

The CME was probably associated with a M3.0 flare from AR 9042, located at
about N23 W62. EIT observed this flare at 14:36. Much of the associated
activity in EIT was very close to the W limb.

Best wishes,
