LASCO Activity Report for
May 10, 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.

2004/05/07 (Friday)

10:50 UT  ESE Limb	Bright loop front and trailing material. Extremely
			faint extensions over the NW limb by 11:50 UT. 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.

15:06 UT  W Limb	Fairly faint 'legs'  over the N and S Pole of an
			apparently very wide loop front. Loop front itself on W
			Limb barely visible. By 15:26 UT ragged front develops.
			Event could be associated with a C1.0 X-ray flare 
			reported by GOES that occurred on NOAA AR 10605 (by the
			time located at S11W36) between 13:37 - 14:23 UT with
			peak emission at 14:03 UT.

17:26 UT  NN West	Ragged loop front.

18:50 UT  N East	Slow development of a system of loops along streamer.

21:26 UT  E Limb	Ragged asymmetric loop ('spray-like') front.
 

2004/05/08 (Saturday)

02:26 UT  S Pole	Asymmetric loop with a diffuse front.

10:26 UT  N East	Very faint front. By ~16:50 UT a fairly faint asymmetric
			front can be seen, one leg along the streamer, the 
			other one close to the N Pole.

12:26 UT  W Limb	Spray-like front.

22:26 UT  WS West	Narrow ragged front.

23:26 UT  S East	Faint and narrow spray front.

2004/05/09 (Sunday)

00:26 UT  N West	Ragged front that fades close to the inner edge of C3.

05:26 UT  N East	Very small and narrow ragged front along the streamer
			that davelops as an asymmetric loop front. It is 
			followed by a similar feature at ~12:06 UT.

08:26 UT  S West	Ragged loop front.

14:06 UT  ES East	Faint diffuse front followed at ~ 18:26 UT by a ragged 
			front. Faint extendion over the E Limb up to the 
			streamer on NE.

20:50 UT  W Limb	Spray-like front.

2004/05/10 (Monday)

04:50 UT  W Limb	Wide and bright ragged lopp front with structured inner
			part. B1.9 X-ray flare reported by GOES on NOAA AR 10604
			(located by the time at S19W29) between 03:48 - 04:04 UT
			with peak emission at 03:55 UT.

06:50 UT  EN East	Faint spray-like front that fades throughout C2. It is
			followed slightly to S at 07:27 UT by a very narrow
			ragged loop front.
