LASCO Activity Report for
April 05, 2004 SOHO Science Daily Meeting

Event times are first frame seen in C2 camera unless otherwise noted.
These are preliminary observations for the daily SOHO science discussions.
Final analysis is reported on the Lasco CME list.
An archive of these reports is available.

Points Of Interest

SOHO is back now from the telemetry keyhole, again with high rate 
telemetry.

After bakeout, EIT synoptic observation program resumed on 04/05/2004 
at 00:24 UT.

2004/04/02

03:00 UT  S East	Ragged front slightly to N of slow-development-of-
			faint-system-of-loops event reported to start at 
			21:40 UT on previous day, and much faster.

04:40 UT  N East	Small ragged front in the trailing material of the 
			'flux-rope' event reported to start at 23:05 UT on
			previous day. Another one at 07:20 UT.

10:41 UT  N East 	Faint ragged loop front. Development missed because  
			of following data gap.
				
	13:20 - 22:20 UT	Data Gap

23:40 UT  S West	Ragged front already in progress after data gap.

2004/04/03

	00:40 - 07:20 UT	Data Gap

07:20 UT  N East	Ragged front already in progress after data gap.

11:00 UT  S East	Bright ragged front.

	16:00 - 24:00 UT	Data Gap

2004/04/04

00:40 UT  S East	Ragged front already in progress after data gap, close
			to the edge of C2 FOV.

01:20 UT  S East 	Ragged front preceded at 00:40 UT by a brighter (and 
			apparently slower) front slightly to S.

	04:00 - 07:00 UT	Data Gap

08:00 UT  W Limb	Small ragged front. It fades throughout C3.

12:20 UT  S East	Faint ragged loop front.

16:20 UT  S West	Couple of fairly faint ragged fronts. They fade
			throughout C3.

16:40 UT  S East	Bright loop front and apparently twisted trailing 
			material.

2004/04/05

01:31 UT  W Limb	Spray-like front follwed at 03:54 UT by another
			spray-like front.

02:54 UT  S East	Ragged loop front slightly to N of previous events. At 
			~04:06 UT it is followed by a brighter loop front at PA
			that matches that of its southern leg. At ~01:13 UT a
			CME is seen in EIT Fe XII running difference images 
			coming out from just behind the SE limb.

06:06 UT  S East	Bright loop front, strong cavity, and trailing material.
			It surpasses previous event by the end of C2 FOV.
			By the time, faint extensions (shock signatures) can be
			seen to NE and SW giving the appearance of a partial 
			halo CME. NOAA AR 0588 (located S18E35) produced an
			M1.7 X-ray flare starting at ~05:37 UT with peak 
			emission at 05:55 UT. The flare could be most likely
			related to the event.

	12:45 - 18:00 UT	Temporary DSN Data Gap
