LASCO Activity Report for
June 2, 2005 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

* Mercury entered the C2 FOV from the right on 2005/06/02 @ 00:32 UT.

* 2005/05/30 - 2005/06/03 between 06:00 - 09:00 UT:  
  C2 Plumes Study: "Microflares, Jets and Macrospicules in and Around PCH".
  During this time: C2 orange/clear subfield images at a 5 min cadence.  
  FOV 14x16 LOCS block region over the South Pole.
  --> No LASCO CME watch during the time of the run.

* 2005/05/28 - 2005/06/05: LASCO Extra PBs for 3D CME Study.
			   During this time (for the CME watch): 
			   - only 1 C2 Orange/Clear per hour;
			   - only 1 C3 Clear/Clear per hour; and
			   - No EIT CME Watch (only synoptic: 4 EIT 195 per day).

* Medoc Campaign started on May 16. Since then SOHO is in Telemetry submode 5.

2005/06/01 (Wednesday)

03:32 UT  ES East 	Big and bright loop front, with bright interior. GOES
			reported an impulsive M1.7 X-ray flare on NOAA AR 10772
			(S18E49) between 02:36 - 02:46 UT with peak emission at
			02:43 UT. A C1.2 X-ray flare on the same AR follows
			(S18E48), between 04:34 - 04:47 UT with peak emission
			at 04:42 UT.

	06:00 - 09:00 UT	C2 Plumes study. NO LASCO CME watch images. 
				(see on top "Points of Interest").

09:32 UT  E Limb	Apparently another CME followed the one reported at
			03:32 UT: Ragged front under development after data
			gap. GOES recorded a C2.0 X-ray flare form NOAA AR 10772
			(S18E47) between 06:57 - 07:09 UT with peak emission
			at 07:04 UT.

11:32 UT  E Limb	Bright and ragged loop front in the trailing material 
			of previous event. GOES reported an impulsive C2.3 
			X-ray flare on NOAA AR 10772 (S17E45) between 10:41 -
			10:57 UT with peak emission at 10:51 UT followed by a
			couple of C1.0 X-ray flares from the same AR peaking
			at 11:49 and 12:46 UT. Please note that also a couple 
			of B-class flares occurred on the same AR peaking at
			09:42 and 08:40 UT. 

18:32 UT  E Limb	Bright and small front just appearing. By the time of
			the following frame (20:32 UT) only some apparent 
			(faint) trailing material can be discerned. No clear
			signatures in C3. GOES recorded the following impulsive
			X-ray events from NOAA AR 10772 by the time:
		        - a C3.1 X-ray flare (S18E41) between 17:46 - 17:58 UT
			  peaking at 17:55 UT, and
			- a C5.9 X-ray flare (S16E40) between 18:00 - 18:21 UT
			  peaking at 18:11 UT.

2005/06/02 (Thursday)

00:32 UT  E Limb	Bright ragged front already half way to the end of the
			C2 FOV. GOES recorded a C7.2 X-ray flare late on
			previous day from NOAA AR 10772 (S17E38), between
			22:03 - 22:25 UT with peak emission at 22:18 UT.

02:32 UT  E Limb	Small front just appearing. It develops as a bright
			ragged front by 03:32 UT.

	06:00 - 09:00 UT	C2 Plumes study. NO LASCO CME watch images. 
				(see on top "Points of Interest").

13:32 UT  E Limb	Another bright ragged front.

Time of the last C2 image analyzed: 13:32 UT.
