October 23, 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.

00:54 UT S East Fairly narrow bright front with cavity,
small bright core and much trailing material
03:54 UT S East Wide bright fast loop front with strong
cavity and small bright structured core.
Possible very faint extensions over N pole
to NW to resemble partial halo CME. Limb
or backsided event
07:54 UT PARTIAL Fairly slow wide bright loop front in NW
HALO develops to ~220 deg partial halo from
S to NE by 10:30 after component in S first
appears at 09:54. Frontsided event, filament
channels activated and destabilised by wave(?)
associated with M3.7 X-ray flare from as-yet
unnumbered AR on/over SE limb
15:30 UT E Limb Narrow ragged front with some gusty outflow
16:30 UT E Limb Asymmetric loop front with slight cavity
follows previous event
17:06 UT E Limb Very narrow ragged front slightly to S
of previous events
20:06 UT E Limb Thick bright loop front with cavity and slight
core and much trailing material, possible very
faint extension over N pole
2003/10/23
02:54 UT E Limb Narrow ragged front with cavity and some
gusty outflow, another follows at 06:06
07:31 UT E Limb Narrow nebulous front, quite bright,
slightly faster than previous events
08:54 UT HALO Fast thick wide bright loop front with strong
(Partial?) cavity and small bright structured core.
Faint extensions over N and S pole and possible
extremely faint extensions in W. X5.4 X-ray
flare AR 0486 S16E75, much associated activity
in and around AR 0484 centered N04E13
