Points Of Interest
Planet Mercury visible in C3 images, moving right to left
2002/04/05
11:54 UT N West Faint system of loop fronts, quite slow,
spans ~140 deg over N Pole by 13:54. No
EIT event so most probably backsided
22:26 UT N West Fairly bright fan
2002/04/06
02:06 UT E Limb Narrow ragged front along faint streamer
03:34 UT N Pole Faint fronts from NNE to NNW
06:50 UT S East Sequence of loop fronts, fairly narrow
and faint, cavity follows
17:06 UT N West Faint ragged loop front along streamer
21:26 UT Partial Bright loop front over E limb and marginally
Halo to S, eventually spans ~200 deg from PA 280
- 120. Bright in E and into NE, fainter over
pole and in NW. Bright loops follow in E

00:06 UT S East Bright fan-like front, quite fast.
Cavity follows
00:26 UT N East Bright ragged front, fairly fast. Further
fronts from 03:26 then prolonged outflow for
rest of day
10:26 UT S West Extremely faint loop front, quite wide
14:50 UT S East Narrow loop front disrupts nearby streamer,
cavity follows
21:26 UT S East Ragged loop front, narrower and fainter than
previous event, and further N
2002/04/08
03:06 UT Partial System of faint loops fronts, wide and slow,
Halo initially in SE but eventually spanning ~150 deg
up into NW
