14:06 UT HALO Event began in C2 at 14:06 UT as an asymmetric loop front
with core centered over PA 269 degrees. The CME consisted of 3 components
in C2; main loop with core in SW at PA 261, the expanding loop to the south,
and a burst in the NNW at PA 333, expanding at approximately the same
acceleration. Material is seen from PA 124 - 9 degrees for a total coverage
of 245 degrees wide. The event continues into the C3 field beginning
at 15:42 UT. The CME tracked through the field to the last frame
while in progress at 21:42 UT to 17.9 Rsun. Speeds. 397.4. Km/sec at
position angle 261 degrees. Click Here for HALO report and movies
