LASCO Activity Report for
February 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
None today.
2002/02/22
02:06 UT S West Faint narrow ragged front
04:54 UT N West Faint front followed by brighter slower loops.
Wider and to N of 21:30 event
09:30 UT N West Wide bright front along streamer. Cavity and
some core-like material follow
09:30 UT S West Multiple loop front with cavity and some
trailing material. Distinct from previous
event, also somewhat slower
20:30 - 23:45 UT No regular images while calibration
set is taken
2002/02/23
09:06 UT N West Initially bright loop front resolves to
faint front and bright slow loops
09:54 UT N East Faint spray, quite wide
13:54 UT S West Fairly bright narrow loop front along
streamer. Some trailing material
17:30 UT S West Wider brighter faster front from same/nearby
source region. Cavity and core follow, and
some gusty outflow
2002/02/24
00:30 UT S West Slow narrow loop system somewhat to N of
previous two events. Loops brighten and widen
through C2 during ~12 hr passage
08:06 UT N East Fast narrow spray
13:31 UT N East Narrow bright front along streamer,
to N of previous event
15:30 UT W Limb Ragged structured loop front fades and
disintegrates through C2. Cavity and
core-like material follow, also possible
very faint extension up to N Pole
17:30 UT N East Narrow bright front with cavity and core.
Same nearby/region as 08:06 event, follows
very narrow, slower event at 15:54
18:30 UT N West Extremely faint loop front spans NW quadrant.
Another at 20:30
2002/02/25
00:30 UT S West Initially very narrow bright slow blob widens
and resolves to slow narrow loop system which
moves through C2 in >12 hrs. Similar to 00:30
event from previous day
10:30 UT W Limb Asymmetric loop front, brightest to S and
with some fainter core-like material there
11:30 UT N West Ragged front with cavity, fairly wide and fast
