LASCO Activity Report for
October 2, 2001 SOHO Science Daily Meeting
Planner: K. Schenk, G. Lawrence
Event times are first frame seen in C2 camera unless otherwise noted.
These are preliminary observations for the daily SOHO science discussions.
Final analysis is reported on the Lasco CME list.
An archive of these reports is available.
Points Of Interest
Proton levels back to serious contamination levels in both
C2 and C3 following the proton event on 2001/10/01
2001/10/01
00:54 UT N West Initially very bright loop front fades through C2
01:54 UT S West Fairly wide bright loop front, slower loops follow
05:30 UT S West Thick wide fast bright front with cavity and core.
Spans ~100 deg but streamers to N and S disrupted
and a faint shock extends over the pole to the
N East so it looks like a full halo. M8(?) on/over
S West limb. Continued gusty outflow over S West
for next 24+ hrs
C2 Running Difference movie
12:54 UT N West Narrow bright feature widens to angular front
with cavity through C2
17:06 UT S Pole Narrow loop front with cavity, a little to the W
21:54 UT N East Bright loops emerge slowly along wide bright
streamer which then proceeds to blow out. Still
in progress at time of writing
22:30 UT N West Brightest and largest of several blobs/narrow fronts
23:06 UT S East Narrow ragged front with some gusty outflow
2001/10/02
07:31 UT N West Bright front along streamer, still in progress
at time of writing
07:55 UT - time of writing Temporary data gap
