LASCO Activity Report for
September 4, 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
EIT CCD bakeout now ended, regular EIT observatons
from 2002/09/03 21:30 UT
2002/09/03
00:25 UT N East Narrow loop front fades through C2
01:25 UT N East Small bright blob along streamer appears
to catch, brighten and accelerate faint
slow-moving disconnection feature at ~4 Rs
02:05 UT W Limb Ragged loop front disintegrates and fades
through C2
08:30 - 15:00 UT Temporary DSN data gap
<15:05 UT S East Nebulous multiple loop front system,
fairly faint
16:25 UT W Limb Ragged loop front and cavity along streamer,
another at 19:25
19:59 UT W Limb Narrow but thick bright loop front with
cavity, follows previous events, faster
23:54 UT E Limb Very faint loop front, quite wide
2002/09/04
00:06 UT W Limb Another ragged loop front with cavity
01:31 - 04:30 UT Temporary DSN data gap
04:54 UT W Limb Bright loop front, quite wide and asymmetric,
cavity and some trailing material. Most
substantial of all W limb events today
06:54 UT E Limb Initially bright loop front fades through C2
08:54 UT N East Moderately narrow but fast, bright front
along streamer enhances and accelerates slow
core-like region from previous event
11:30 UT E Limb Moderately bright loop front, similar width
to 06:54 event but brighter and more coherent.
Brightest in NE probably due to integration
with part of 08:54 event
