LASCO Activity Report for
February 23, 2004 SOHO Science Daily Meeting
Planner: K. Schenk, G. Stenborg
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
2004/02/20
N East Gusty outflow all day long.
S West Continuous (slow) expansion of loops' system along
streamer all day long leading to partial streamer
blowout.
02:30 UT S East Fairly faint ragged asymmetric loop front to N of event
at 18:30 UT on previous day, followed at 10:54 UT by
another smaller one.
06:30 UT S West Extremely faint ragged front to S of streamer with
faint loop-shaped extensions over the streamer.
10:30 UT W Limb Extremely faint and narrow spray front. It fades in C2.
12:30 UT E Limb Extremely faint ragged front. It fades in C2.
14:30 UT S Pole Faint, narrow and long spray-like front.

N East Gusty outflow all day long, most probably related to
activity on NOAA AR 0564.
00:06 UT S West Small ragged front followed by gusty outflow.
06:54 UT N East Small ragged front to S of gusty outflow.
15:30 UT S West Faint ragged front developing toward S, to S of gusty
outflow. It fades throughout C3.
2004/02/22
N East Gusty outflow all day long, most probably related to
activity on NOAA AR 0564.
02:30 UT N East Faint ragged front. Barely discernible in C3.
03:30 UT S West Faint ragged front developing towards S, to S of gusty
outflow. It is followed at ~ 09:54 UT by another faint
ragged front. At 12:30 UT material is seen falling
down starting at ~ 3.65 solar radii (PA ~ 186).
09:54 UT N East Faint raged front.
15:30 UT W Limb Bright asymmetric ragged loop front much brighter to N.
17:54 UT W Limb Bright loop front with cavity and inner core slightly
to N of previous front, developing towards NW. Twisted
trailing material.
18:54 UT S West Small and faint ragged front going out, and small blob
falling down. Separation point at ~ 3.1 solar radii
(PA ~ 198).
2004/02/23
00:30 UT N East Fairly faint ragged front. Material is being pushed
aside to N since earlier.
04:06 UT N West Blob-like front.
05:06 UT N East Ragged front.
08:30 UT E Limb Raged loop front developing slightly toward S.
