LASCO Activity Report for
April 07, 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.

Points Of Interest

2004/04/06

00:30 UT  W Limb	Spray-like front developing slightly toward SW, followed
			by a couple of ragged fronts (e.g., 04:54 UT, 09:30 UT).
			They all fade throughout C3.

06:06 UT  S Pole	Fairly faint and small spray-like front developing
			slightly toward SW. It fades throughout C2.

08:30 UT  S Pole 	Fairly faint and small spray-like front developing
			slightly toward SE. It fades throughout C2.

11:30 UT  W Limb	Fairly faint ragged front developing slightly toward NW.
			In C3 only barely visible close to the inner edge.

13:31 UT  HALO		Bright loop front appears above SE limb; by 14:06 UT 
			the front has developed into a full halo CME, though
			rather faint in the NW.	The front first appeared in C3
			images at 14:18 UT with full coverage of the C3 
			occulting disk by 15:18 UT. The mean plane-of-sky speed
		 	at PA 163 was 1075 km/s showing a slight positive
			acceleration in C2 FOV and a slight deceleration in C3
			FOV. Most probably associated with a M2.4 X-ray flare
			that GOES records from AR 0588 (by the time at S18E15) 
			between 12:30 - 13:46 UT with peak emission at 13:28 UT.
			Clear signatures of the event in EIT Fe XII running
			difference images between 12:36 and 15:48 UT, the flare
			peaking at 13:25 UT.

19:54 UT  S Pole	Faint and diffuse loop front, immediately preceded by
			another faint front slightly to SE that quickly fades.

22:06 UT  W Limb	Faint ragged front developing slightly toward SW. It
			fades in C3.

23:54 UT  W Limb	Spray-like front developing slightly toward NW. It fades
			in C2.
