08:06 UT W Limb Narrow front fades through C2
20:06 UT W Limb Ragged amorphous front disintegrates
and fades through C2
19:31 UT N East Ragged fronts follow very slow loops along
streamer that has been swelling and
brightening for several hours, leading
to partial blowout
20:30 UT S East Narrow jet, quite slow

08:06 UT W Limb Wide bright loop front with large cavity
and small bright core. Much gusty outflow
for most of day including fronts from

10:57 UT S East Narrow asymmetric loop front with
slight cavity
15:54 UT N East Moderately faint wide nebulous loop front
with much trailing material including
some narrow fronts
19:31 UT W Limb Sequence of moderately narrow ragged
loop fronts, gusty outflow follows

23:08 UT N West Bright loop front, fairly fast and wide,
cavity and core follow. EIT eruptive
prominence on limb

11:08 UT S West Initially bright loop front resolves to
multiple loop system, quite slow
2003/02/18
02:42 UT N West Fast wide bright loop front with large
cavity and bright structuresd core, much
gusty outflow into next day. Large EIT
eruptive prominence in NW
12:42 UT S West Fast spray-like front, fairly wide and bright
2003/02/19
02:42 UT N West Narrow ragged spray-like front
07:47 UT N West Fairly wide well-defined loop fronts begin
to rise extremely slowly along wide bright
streamer complex leading to partial blowout
13:47 UT S West Ragged front along streamer
