00:26 UT N East Sequence of ragged loop fronts and cavities,
some gusty outflow follows. Moderately wide
03:26 UT S West Sequence of faint loop fronts, brightest
towards centres. Slight cavities follow
05:26 UT S East Narrow front along streamer, bright and
well-defined. Followed by
07:27 UT S East Bright loop front with cavity and bright
structured core. EIT eruptive prominence.
Followed by
09:50 UT HALO Bright well-defined loop front in SE is
full halo CME by 10:06 UT, although
emission over N pole is faint. Brightest
from SW to NE, streamers in SW and NE
disrupted. Huge EIT eruptive prominence
reaching to ~ E45 and with obvious
non-radial expansion/propagation
14:50 UT N West Ragged loop front with cavity
15:06 UT HALO Faint loop front in S hemisphere is
followed by bright, highly structured
core-like material in ESE, some core-like
material in S and into SW. EIT eruptive
prominence over ESE limb
18:06 UT N West Wide bright thick loop front with large
cavity and some trailing material,
quite fast
19:27 UT S West Nebulous front with cavity
22:06 UT N East Ragged front along streamer, brightest
towards S
22:26 UT S East Narrow ragged front, quite faint
2002/10/26
04:06 UT N West Bright loop front, fairly fast and wide.
Cavity and some trailing material follow
07:27 UT Partial Fast bright loop front in SE spans ~200 deg
Halo from NE to SW by 08:06. Possible extremely
faint extensions in rest of field of view
but only visible in running difference
images. Backsided event
12:26 UT S Pole Faint narrow front
20:50 UT S East Very slow ragged loop front along streamer,
quite faint
2002/10/27
05:50 UT N East Narrow jet-like front, quite slow
06:50 UT N West Spray-like front with cavity
09:06 UT N East Narrow loop front along streamer, another
at 10:50
09:26 UT S Pole Sequence of loop fronts, some asymmetric
10:06 UT N West Ragged front along streamer, slight
cavity and core-like material follow
14:06 UT N East Nebulous front fades through C2
14:50 UT S East Moderately bright loop front with
slight cavity, further fronts follow
16:06 UT E Limb Fairly wide bright spray-like front
with slight cavity
18:06 UT N West Sequence of faint loop fronts
18:26 UT N East Ragged front along streamer
21:26 UT S West Faint ragged front along streamer
21:50 UT S East Narrow fan
22:36 UT N East Bright ragged front, EIT limb eruptive
prominence, soon obscured by
23:26 UT HALO Bright front in SE quadrant spans ~220 deg
from SW to near N pole by 23:50. Streamers
in NE and SW disrupted. Faint extensions in
NW quadrant. Much prolonged outflow in SE.
Backsided event

cavity follows
