LASCO Activity Report for
May 31, 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.

* 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).

* 2005/05/27: EIT CME watch in 304 between 00:00 - 24:00 UT.

* Medoc Campaign started on May 16. Since then SOHO is in Telemetry submode 5
(until June 3 afternoon UT).

2005/05/27 (Friday)

00:50 UT  SS West	Expanding loop front. Note that by 23:50 UT on previous
			day a thin brightening can already be guessed. It is
			followed at 02:26 UT by a narrower front moving
			apparently faster. The event partly superposes in the
			LOS with some small ragged fronts and gusty outflow
			under development on WSW.

06:26 UT  ES East	Ragged loop front followed at 07:26, 08:26, 09:50, 
			11:26, 17:50, and 21:26 UT by similar (though some
			narrrower) fronts.

08:06 UT  N West	A ragged front develops behind the faint system of 
			loops under development since early on previous day.

08:50 UT  S West	Asymetric (spray-like) loop front. Difficult to give
			an exact time of first appearance. It is followed at
			10:50 UT by a faint and elongated loop front a little
			bit to S. By 13:26 UT, a couple of faint 'half loop'
			fronts expanding toward WSW develops. Some small blob-
			like fronts by the end of the day. All these features
			fade throughout C3.

15:26 UT  N West	Very faint and ragged front. Some small ragged blob-like
			fronts follow during the rest of the day, all of them
			fading throughout C3.

2005/05/28 (Saturday)

03:32 UT  ES East	Very faint and elongated loop front that apparently
			fade before reaching the C3 FOV.

09:32 UT  E Limb	Not-well defined and faint front followed at 13:32 UT
			by a similar one. Both fronts fade throughout C2.

07:32 UT  WN West	Faint and not-well-defined front. It fades throughout C3.

13:32 UT  WN West	Ragged and elongated blob-like front.

15:32 UT  S East	Ragged front. It fade throughout C3.

16:32 UT  E Limb	Ragged loop front coming behind event at 13:32 Ut (see
			entry at 09:32 UT). Difficult to give an exact time
			of first appearance.

2005/05/29 (Sunday)

00:32 UT  S East	Ragged front that fades throughout C3.

11:32 UT  N West	Faint and expanding (slow) loop front. Several blob-like
			fronts to south developing faster.

12:32 UT  E Limb	Elongated brightening (spray-like) preceding at 
			15:32 UT a bright and ragged loop front.

2005/05/30 (Monday)

00:32 UT  E Limb	Another bright loop front (brighter than the one at 
			15:32 UT on previous day).

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

09:32 UT  W Limb	Big loop front already at the end of the C2 FOV. GOES
			reported no significant X-ray activity by the time.

13:32 UT  EN East	Diffuse front develops as a wide and expanding ragged 
			loop front. By 16:32 UT, an elongated (and relatively
			narrow) front follows on ENE. The outer front of the
			event spans almost 120 deg, from a little past the N 
			Pole to around PA 120 deg. All features observed fade
			throughout C3.

19:32 UT  WN West	Narrow ragged loop front.

20:32 UT  ES East   	Ragged loop front just a little bit to N of the southern
			leg of the wide expanding loop front at 13:32 UT. It 
			moves apparently faster than the features described in
			entry at 13:32 UT. This front on ESE is preceded by a
			faint and diffuse front. It fades throughout C3.

2005/05/31 (Tuesday)

04:32 UT  W Limb	Slow development of a faint system of loops.

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

Time of the last C2 image analyzed: 12:32 UT.
