LASCO Activity Report for
March 4, 2002 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
None today
2002/03/01
00:06 UT N West Faint narrow ragged front along streamer
02:30 UT S West Fairly wide bright loop front, quite fast.
Small cavity follows, then core in several
sections. Streamer disrupted to S, also faint
fronts extend up to N Pole and remove large
part of diffuse streamer complex
04:54 UT S Pole Narrow ragged front along disrupted streamer,
possibly destabilised by earlier CME
18:54 UT S West Ragged front with cavity and some outflow
19:54 UT S Pole Narrow loop front along wide bright streamer,
quite bright
20:30 UT S East Narrow ragged front with cavity
21:54 UT N East Narrow ragged front along streamer, quite
ragged and slow, with bright central region.
Faint fronts follow
2002/03/02
01:31 UT S East Bright narrow front with cavity
07:31 UT S West Faint narrow ragged front
13:31 UT S East Another bright narrow ragged front with cavity,
slower and further N than 01:31 event
15:06 UT S East Wide bright loop front with cavity and highly
structured core, spans ~120 deg by 16:06. EIT
eruptive priminence, outflow in SE for ~24 hrs.
S Pole streamer disrupted, gusty outflow follows
there for several hours
20:58 UT N West Nebulous front with cavity, quite narrow. C4.7
flare N14W23. Wider faint front follow
21:30 UT S East Wide loop front with cavity and some bright
core-like material. Brightest over S Pole.
Limb/backsided CME, this and previous events
together resemble a halo CME in ratio images
2002/03/03
00:54 UT N West Narrow bright front along streamer, fades quickly
08:54 UT S West Sequence of faint fronts, quite narrow
2002/03/04
04:54 UT N West Narrow jet, quite fast and bright
07:31 UT N West Narrow loop front with cavity, to S of
previous event. Smaller fronts follow
