LASCO Activity Report for
June 14, 2004 SOHO Science Daily Meeting

Planner: K. Schenk, G. Stenborg

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

VENUS is no longer visible in C3. It exited the C3 FOV on 2004/06/13 
(Sunday) at ~ 05:18 UT.

MERCURY entered the C3 FOV (from the right) on 2004/06/12 (Saturday).

VENUS reappeared in the C3 FOV at around 07:00 UT on 2004/06/09 (Wednesday).

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.


2004/06/11 (Friday)

	  N East	Gusty outflow all along the day.

03:06 UT  N West	Kind of reconexion event starting close to the
			inner edge of C2. Very faint front follows. They fade
			throughout C3.

04:50 UT  E Limb	Extremely faint and diffuse loop front. It fades
			throughout C2.

12:26 UT  ES East	Diffuse loop front that quickly fades (in C2).

16:26 UT  WS West	Extremely faint elongated (sharp) loop front. Not
			discernible in C3.

19:27 UT  W Limb 	Kind of blob-like feature. Couple of other 'blobs' 
			early on next day. They all fade close to the inner 
			edge of C3.
	 

2004/06/12 (Saturday)

05:26 UT  W Limb	Ragged and diffuse loop front. It fades throughout C3.

14:06 UT  EN East	Faint front superposed in the LOS with the slow
			development of an apparent system of loops above NE.

2004/06/13 (Sunday)

	  N East	The slow development of the system of loops reported
			in entry at 14:06 UT on previous day, continues. At 
			~ 07:50 UT a twisted feature is discerned. By 16:50 UT,
			a feature that develops as a kind of 'V-shaped' front
			is first guessed apparently superposed in the LOS with
			the other features mentioned.

14:06 UT  E Limb	Diffuse front followed at 14:50 UT slightly to N by
			another diffuse and slightly brighter diffuse and
			ragged front. They fade close to the inner edge of C3.

23:26 UT  WS West	Bright ragged loop front. Twisted trailing material.

2004/06/14 (Monday)

	09:50 - 12:05 UT	Temporary DSN Data Gap.
