LASCO Activity Report for
March 12, 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.

Points Of Interest

2004/03/11

	  S East        Much outflow.

07:31 UT  N East	Diffuse and very faint front extending all over the 
			N Pole up to the NW limb showing a very slow 
			development. It is first seen in C3 at 16:18 UT. No
			likely related signatures visible in EIT Fe XII images. 

11:06 UT  W Limb	Small ragged front jointly with a jet-like front. They
			fade throughout C2.	

17:06 UT  S East	Bright ragged loop front and trailing material
			(difficult to give precisely the time of first
			appearance). At 19:42 UT is first seen in C3, moving 
			much faster than the event reported to start at 
			07:31 UT. Both events together give the appearance of 
			a 'partial' halo CME. Gusty outflow.

19:31 UT  W Limb	Extremely faint front barely visible in C2. EIT Fe XII
			running difference images show CME coming from just
			behind the W Limb at around 19:13 UT. An extremely 
			narrow ragged front slightly to S developing toward SW
			appears in C2 FOV at 20:06 UT.			

20:30 UT  N Pole	Faint and wide loop front. At around 00:30 UT on next 
			day at the PA of its leg on the NE limb, a faint
			asymmetric loop front develops.

00:30 UT  N West	Extremely faint diffuse front moving faster that a
			bright ragged front following at ~ 01:31 UT. Due to 
			the superposition of both events on the line of sight, 
			it is difficult to give an accurate time of first
			appearance for the second event. EIT HE II images show
			the eruption of a a huge prominence coming out from
			behind the NW limb (first seen at 19:19 UT on previous
			day, next image at 01:19 UT). Huge twisted structure
			after data gap.

	06:50 - 11:40 UT	Temporary DSN Data Gap
