LASCO Activity Report for
March 08, 2004 SOHO Science Daily Meeting

Planner: K. Schenk, G. Stenborg

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





2004/03/05

04:54 UT  N West	Blob-like front starting at ~ 4.4 solar radii.

05:30 UT  S East	Couple of fairly faint ragged fronts developing 
			towards S. They fade close to the inner edge of C3.

06:06 UT  W Limb	Very faint ragged front. It fades throughout C2.

15:30 UT  W Limb	Elongated and diffuse loop front developing toward 
			SW, followed at: i) ~ 17:30 UT, at the same PA, by
			another elongated loop front, and trailing material;
			ii) ~18:30 UT by a ragged front developing toward W; 
			and iii) ~22:30 UT, slightly to N, by another ragged
			front. They all fade throughout C3.
	
18:30 UT  E Limb	Extremely narrow ragged front developing toward SE.
			It fades throughout C2. Follow several spray-like 
			fronts slightly to S that fade very close to the inner
			edge of C3. In particular, at ~21:08, ~00:06, and 
			~04:30 UT, the last two on 2004/03/06.			

2004/03/06

05:54 UT  W Limb	Following event reported to start at 15:30 UT on 
			previous day, ragged loop front followed at 09:54 UT by
			a jet-like front, and at 13:31 UT, slightly to S,
			by a bright spray front developing toward SW. The spray
			front is preceded at 11:54 UT by a diffuse ragged front
			that quickly fades.

07:31 UT  S West	Ragged loop front developing toward S.

20:06 UT  S East	Slow development of loops' system along streamer.
			Difficult to give accurate starting time. It continues
			into next day.

20:30 UT  S Pole	Ragged front followed at 22:06 UT by another ragged 
			front to SW. By that time and over the S Pole a faint 
			asymmetric loop front with twisted inner structure
			develops, fading throughout C3.

2004/03/07

06:06 UT  W Limb	Ragged front developing slightly toward NW.

07:31 UT  W Limb	To S of previous event, bright ragged and diffuse 
			front developing toward SW. It fades throughout C3.

09:54 UT  S East 	Bright loop front followed by a complex inner structure.
			At ~09:00 UT EIT Fe XII running difference images show 
			a CME coming out fromt just behind the SE Limb. By the
			time no dimming is seen on the disk. The event disturbs
			the slow development of the event reported to start at
			20:06 UT on previous day. The resulting fronts are seen 
			to extend over the SW limb, giving the appearance of a
			partial halo CME.

15:54 UT  N East	Jet-like front.

18:30 UT  N East	Ragged front and twisted structure slightly to N of
			previous event.

2004/03/08

02:54 UT  W Limb	Extremely narrow ragged front followed at 06:30 UT by
			another ragged front. They fade throughout C2.

06:54 UT  W Limb	Very faint loop front extending over SW (central axis
			at PA ~ 245). Between 05:36 and 09:38 UT, EIT Fe XII 
			show the development of a CME originating on NOAA AR
			0569, which is located slightly W of the central 
			meridian (~20 deg) at about 11 deg S latitude.
