LASCO Activity Report for
September 22, 2003 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.

08:54 UT W Limb Slow narrow front disintegrates through C2
14:54 UT W Limb Sequence of ragged loop fronts and slight
cavities to N of previous event
17:54 UT S West Ragged front along streamer, quite bright
2003/09/19
12:30 UT E Limb Faint narrow ragged front fades and
disintegrates through C2
2003/09/20
04:30 UT W Limb Fast wide bright loop front with cavity
and core and plentiful outflow
09:30 UT W Limb Another fast wide bright loop front with
cavity and core and plentiful outflow,
very similar to previous event. EIT
eruptive prominence possibly destabilised
by previous event
13:54 UT E Limb Faint ragged asymmetric front
21:54 UT N West Bright narrow front with slight cavity
23:06 UT N West Bright ragged asymmetric front fills
NW quadrant. Backsided event
2003/09/21
03:54 - 08:30 UT Temporary DSN data gap
08:30 UT Partial Wide bright loop front initially fills NW
Halo quadrant spans ~120 deg from SW to NE.
Backsided event. Much prolonged outflow
including faint wide slow loop fronts in
which eventually span down to E limb
17:30 UT E Limb Faint wide loop front
21:06 UT Partial Another wide bright loop front, similar
Halo span to 08:30 event but faster brighter
and rather asymmetric
2003/09/22
00:54 - 03:30 UT Temporary DSN data gap
03:54 UT E Limb Sequence of fairly faint loop fronts with
slight cavities already in progress
03:30 UT N Pole Asymmetric loop front with cavity
03:54 UT W Limb Narrow ragged front
