LASCO Activity Report for
May 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.
Final analysis is reported on the Lasco CME list.
An archive of these reports is available.

Points Of Interest

SOHO Telemetry Submode changed to Submode 5 on 2004/04/13 at 16:00 UT 
(SUMER began observing on 2004/04/14). SUMER campaign runs until 2004/06/17.
In other words, LASCO synoptic observation plan cadence remains the same
but the EIT CME watch images will be reduced to half-resolution (512x512)
during that period.

02:50 UT  N West	Ragged front that quickly fades. Event signature in 
			EIT Fe XII running difference images starting at 
			02:12 UT right on the NW limb. Material moving all 
			along a rising loop.

05:50 UT  E Limb	Ragged loop front that fades throughout C2. Backsided 
			CME seen on E Limb in EIT Fe XII starting at 04:48 UT.

08:26 UT  N West	Another ragged front preceding another similar one at
			11:26 UT slightly to N.

10:50 UT  E Limb	Ragged loop front developing slightly toward SE. Slow
			twisted structure develops behind. Backsided CME 
			(fainter than the previous one) seen in EIT Fe XII 
			at ~ 10:14 UT to S of event reported to start at 
			04:48 UT.

23:26 UT  N West	Wide though faint and diffuse loop front. It fades  
			throughout C3.

2004/05/07 (Friday)

10:50 UT  ESE Limb	Bright loop front and trailing material. Big signature
			of a barely backsided CME in EIT Fe XII running
			difference images above the ESE limb. Intensity 
			disturbance seen traveling toward the S Pole all above
			the SE limb. Wave on disk by 11:12 UT.
