March 22, 2001 SOHO Science Daily Meeting
Planner: K. Schenk, G. Lawrence
Event times are first frame seen in C2 camera unless otherwise noted.

Final analysis is reported on the Lasco CME list.
Points Of Interest
Kreutz sungrazing(?) comet in C3 field of view. It can be seen at
~17 Rs at PA 127 in the 11:42 UT image. Brighter than average.

02:50 UT S West Narrow front along streamer
10:26 UT N East Narrow spray
10:50 UT S West Very faint loops, probably backsided
11:50 UT N West Bright loops/fronts ejected along streamer.
Bright complex prominence material follows,
Further prolonged gusty outflow
15:50 UT S Pole Narrow bright jet
18:50 UT N East Slow ragged front along streamer,
gusty outflow follows
21:26 UT W Limb Sequence of 4 ragged fronts, second is largest
and brightest
2001/03/24
00:50 UT N East Sizeable fronts in gusty outflow from 18:50 event
02:06 UT W Limb Wide bright front with cavity and gusty outflow.
Seperate event from 21:26 though same area
02:50 - 04:26 UT Temporary data gap
07:27 UT S East Large blob/faint front
09:26 UT S East Faint loop front, backsided?
13:27 UT S West Ragged front along streamer
17:06 - 23:59 UT Temporary data gap
2001/03/25
00:00 - 15:26 UT Temporary data gap
15:50 UT E Limb Very large bright blob
17:06 UT N Pole Thin front initiqally bright fades in C2. Fainter
extensions to ~PA120 and possibly to ~PA160 so
possible partial halo.
19:27 UT E Limb Vary faint ragged front
2001/03/26
00:26 UT W Limb Slow bright ragged front along narrow faint
streamer. Prolonged outflow includes cross-hatching
05:50 UT N East Faint ragged front/fan followed by flux ropes
12:50 UT W Limb Faint loop(s)
