LASCO Activity Report for
November 5, 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
Timings given below are approximate, correct to ~10 mins, due to
a subset of the high-cadence LASCO campaign, taken during the EIT
bakeout, being analysed at this preliminary stage.
Data from ~17:30 UT 2001/11/04 are badly degraded due to an ongoing
proton storm.
2001/11/02
06:06 UT N East Faint narrow ragged front
11:54 UT N East Narrow bright ragged front along streamer
12:30 UT S West Wide bright loop front with cavity, arcades
and some corelike material
21:54 UT N East Fairly wide bright loop front
2001/11/03
03:10 UT N East Slow ragged front along streamer
07:35 UT S West Bright front overtakes slow loops along streamer
12:05 UT Partial Fairly faint loop front first seen over N and S,
Halo is ~180 deg partial halo by 12:35. Slow event,
looks like an eruptive prominence
17:35 UT S West Bright narrow front with cavity and core
18:35 UT Halo Wide bright front spans from N West to E Limb,
is full halo CME by 20:35 though faint in S
and S West. Corelike material follows in N
2001/11/04
07:35 UT N Pole Very faint loop front, quite wide
13:05 UT S East Faint narrow front
16:35 UT Halo Fast wide bright front over W limb is full halo
CME by 17:05. X1.0 flare from AR9684, N06W18.
Proton storm follows and subsequent data is
badly degraded. Much gusty outflow in S West,
may be residual to this event but could be distinct
