LASCO Activity Report for
July 8, 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 now removed
during standard image processing
C2 high-cadence pB sequence campaign now running.
C2 pB sequences being taken every hour at the expense
of 1 normal C2 image and 1 normal C3 image.
Campaign runs to 2002/08/02 (possibly later, TBD)
2002/07/05
00:54 UT S West Faint fan-like front, fades through C2
02:54 UT S East Faint narrow loop front along streamer
04:30 UT S West Fairly wide bright loop front with
some trailing material and bright
core-like region to follow
13:31 UT W Limb Thick bright loop front, quite wide and
fast, streamer in SW disrupted
22:06 UT S West Sequence of fairly wide loop fronts
along/near streamer, quite bright and
fast. Some continued outflow
2002/07/06
10:34 UT S Pole Fairly bright nebulous front disintegrates
somewhat through C2. Quite bright and fast
20:06 UT W Limb Bright ragged front along streamer,
some gusty outflow
2002/07/07
05:30 UT S East Narrow ragged front along streamer,
fades quickly
11:06 UT W Limb Wide bright loop front, fairly thick
and fast. Faint extensions to N and S
poles give appearance of partial halo
CME. EIT limb/backsided event. Much
trailing material, some protons
18:06 UT N West Bright loop front originates close to
N edge of previous event. Narrower
and slower than previous event, some
bright complex core-like material follows
23:06 UT W Limb Narrow jet-like front, quite bright
2002/07/08
09:30 UT N East Amorphous blob-like front, moderately
bright
10:42 UT S West Very slow loops begin to move out along
streamer. Blowout in progress?
