LASCO Activity Report for
June 25, 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

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
11:30 UT W Limb Very faint nebulous front
13:54 UT W Limb Moderately bright ragged front, fades
somewhat through C2
17:07 UT N Pole Ragged front along streamer, fades quickly.
Another at 18:30
20:06 UT W Limb Wide loop front, initially quite bright,
