LASCO Activity Report for
June 13, 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

* Telemetry KEYHOLE (SOHO will stay in TM Submode 5 during the Keyhole): 
  2005/06/05 - 2005/06/25: 26 m
  2005/06/09 - 2005/06/20: 34 m

* SOHO Maneuvers: 2005/06/17
  - LASCO safes on 2005/06/16 (Thursday) at 15:30 UT.
  - Station keeping, Momentum management, and 180 deg Roll on 2005/06/17
    (burns should be complete by ~15:55 UT).
  - LASCO recovery on 2005/06/18 (Saturday) at ~18:00 UT (or slightly earlier). 

* During the KEYHOLE, LASCO will be in synoptic improved program (12 min 
  cadence C2, 30 min cadence C3), with little loss of telemetry throughout 
  due to the advanced recorder setup.

* 2005/05/06 - 2005/06/24: EIT Bakeout (==> No EIT CME Watch).
  EIT performed the long pre-bake calset (06/06 15:58-21:45 UT) and went 
  to heaters on at 21:52 UT. EIT will be in bake till June 24 @ 10:00 UT 
  and should resume imaging by (06/24) 20:00 UT.
 

2005/06/10 (Friday)

00:12 UT  N East	Very faint and diffuse front that quickly fades.
	
05:24 UT  S West	Apparently narrow and twisted structure devloping along
			the streamer. Difficult to give an exact time of first
			appearance. Some gusty outflow afterward. 

19:24 UT  S West	Ragged blob-like front starts to form, first seen in C3
			at ~ 20:18 UT. It develops faster than previous event.

2005/06/11 (Saturday)

	
	Mostly quiet.

2005/06/12 (Sunday)

	
02:36 UT  W Limb	Diffuse loop like front [1] followed at 02:48 UT (on WNW)
      (Complex Event)	by a bright loop front [2], and at 03:24 UT (on W) by 
       -frontsided-	another loop front developing slightly toward WSW [3]. 
			By 04:12 UT very faint extensions seem to develop above
			both poles. Feature [1] makes its appearance in the C3
			FOV at 03:18 UT showing up above the W Limb, by 03:42 UT
			[2] starts to be seen above WNW, and by 04:18 UT [3]
			appears on W. By 06:42 UT, very faint extensions above
			the poles can be discerned. GOES reported a long 
			duration C3.0 X-ray event on NOAA AR 10775 (N06W24)
		 	between 01:50 - 05:00 UT with peak emission at 03:15 UT.
			Note that a C3.5 X-ray flare was also reported by the
			time, as happening on NOAA AR 10776 (S06W09) between
			02:30 - 02:48 UT with peak emission at 02:36 UT. 

16:00 UT  WN West	Faint and diffuse front preceding a bright and ragged
			(expanding) loop front at 16:24 UT. GOES reported 
			another LDE event on NOAA AR 10775 (N11W13): a C3.0 
			X-ray flare between 15:07 - 17:59 UT with peak emission
			at 16:09 UT.

23:12 UT  WN West	Small and diffuse front that quickly fades.
	

2005/06/13 (Monday)

	
03:24 UT  WN West	Ragged loop front.

	05:00 - 12:48 UT	Temporary DSN Data Gap.

13:00 UT  WN West	Bright ragged front followed at 13:24 UT by a similar
			one, just a little bit to S.

Time of the Last C2 Image analyzed: 14:36 UT.
