LASCO Activity Report for
June 24, 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
Additional stray light in C3 images. Reason presently unknown.
Note that the data processing for C3 exaggerates the effect
of this stray light - the actual counts in the raw images are
higher, but not extraordinarily so

08:30 UT W Limb Another moderately faint ragged front
along streamer, wider and brighter than
previous event, some trailing material
10:06 UT N East Extremely faint ragged front, another
at 18:30
20:54 UT S West Wide bright loop front with much trailing
material. Further faint loop fronts follow
2002/06/22
11:30 UT S East Faint ragged loop front fades through C2
14:54 UT S West Faint narrow ragged front along streamer,
some trailing material
19:31 UT S West Narrow spray-like front, to N of previous
event
2002/06/23
03:30 UT N West Moderately wide initially bright ragged
fan-like front, fades somewhat through C2.
M1.6 X-ray flare N13W70 (AR 9997?)
2002/06/24
00:54 UT Partial Thin wide bright well-defined multiple-loop
Halo front system in SW eventually spans ~150 deg.
Thin cavity and multiple-loop core follow,
then much trailing material. Slow event
10:06 UT - time of writing Temporary DSN data gap
