Subject: Partial (?) halo CME on 2000/09/05

  ------------------------------------------------------------------------

LASCO and EIT observed a partial halo CME today, 2000/09/05. The event was
first visible in C2 as a loop front over the N pole at 05:54 UT. The CME
later extended at least from PA 300 (NW limb) over the N pole to PA 175 (S
pole). There may also be a faint component along the W limb, which would
make this event a full halo (hence the question mark in the subject line
of this message). The measured speed in the plane of the sky is 362 km/s
at PA 0 (N pole).

EIT observed a filament eruption on the disk in the vicinity of AR 9152,
located about N20 E21. This eruption began at about 04:12 UT.

Images and movies of this event are available at the LASCO ftp server:

Best wishes,

Simon Plunkett.
