02:50 UT S East Extremely faint loop front
05:50 UT N East Wide bright loop front with much trailing
material, fairly fast. SE streamer deflected.
M1.2 X-ray flare AR 0346 N16E66
12:50 UT N West Narrow bright spray
13:27 UT S East Multiple faint fronts with cavities, brighter
and faster than 02:50 event. Some brighter
trailing material to S
16:50 UT N West Ragged front along streamer, some continued
outflow for rest of day
17:26 UT S West Faint loop front fades quickly
18:26 UT N East Faint ragged front along streamer
2003/04/26
01:27 UT N West Ragged loop front along streamer, further
similar fronts at 02:26, 04:26
05:26 UT N East Faint front fades quickly
08:26 UT N West Bright asymmetric front with cavity and some
trailing material, faster and to S of
earlier events. M7 X-ray flare AR 0338?
15:06 UT N West Narrower slower front with cavity follows
earlier event, ragged front follows at 17:06
21:50 UT N East Wide bright loop front with strong cavity
and bright structured core. Large EIT
eruptive prominence
23:26 UT S West Narrow loop front, quite bright
2003/04/27
01:27 UT N West Fairly slow bright front, possibly associated
with ~23:30 UT M2.1 X-ray flare from previous
day?
01:50 UT S West Narrow ragged front along streamer with very
faint extension to S pole
02:50 UT S East Fairly bright spray, another at 15:50
03:26 UT N East Thick bright loop front, quite fast and wide,
large cavity and trailing material follow
04:26 UT N West Thick bright loop front, quite fast and wide,
structured core and further trailing ,aterial
follow. To N of 01:27 event
08:08 UT W Limb Fairly narrow bright loop front with cavity
15:50 UT N West Ragged front along streamer, M1.7 X-ray flare
AR 0338, N21W85?
2003/04/28
03:06 UT S West Initially bright narrow loop front along
streamer fades through C2. Slight cavity
follows
04:50 UT S West Faster wider loop front follows previous
event
