Points Of Interest

Total solar eclipse 2002/12/04, totality at 05:56, 06:19,
06:20 and 09:10 UT, subject to viewing location. LASCO/EIT
somewhat erratic 05:20 - 11:00 UT whilst taking images in
support of 4 independent ground-based expeditions

Eclipse teams - note that gusty outflow from the backsided
full halo CME of 2002/12/02 17:54 UT is visible in the LASCO
field of view for the duration of the eclipse period, mainly
in the NW between PA 270-350 and primarily between PA 320-350.

The bright object to the S in C3 images is 
Alpha-Scorpio (Antares)

2002/12/03

03:06 UT  W Limb	Initially quite faint narrow ragged loop front 
			expands and brightens through C2, slight cavity

10:06 UT  N West	Fairly wide blob and slight cavity, probably 
			part of gusty outflow. Another at 16:06

13:27 UT  N East	Narrow spray-like front with slight cavity,
			quie bright. Another at 20:50, both along
			same evolving streamer around PA 60

20:06 UT  N West	Initially narrow ragged asymmetric front
			widens through C2. A similar but narrower
			front follows at 23:50 around same PA

2002/12/04

01:27 UT  N East	Faint fan along same streamer at PA 60

02:06 UT  N East	Faint asymmetric loop front with slight
			cavity, to N of earlier sprays, centred
			around PA 20. Probably backsided

03:26 UT  N East	Another fairly bright spray, same PA as
			13:27 and 20:50 events, already in
			progress at writing. Another at 08:26 UT

03:26 UT  N West	Another ragged asymmetric front, quite
			similar to 20:06 event, widens and fades
			through C2, just in progress at writing

10:06 UT  N West	Small infalling blob starts from ~2.9 Rs
			around PA 315
