LASCO Activity Report for
July 02, 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

SATURN entered the C3 FOV (from the left) on 2004/06/29 (Tuesday).

SOHO is now in a telemetry keyhole (2004/06/16 - 2004/07/03). LASCO data 
will consist of typically two (occasionally three) continuous periods of
real-time data per day.

EIT 195 CME watch was interrupted on 2004/06/15 (Tuesday) at 15:00 UT
for EIT CCD bakeout calibrations. EIT CCD bakeout started on 2004/06/15 
at ~ 20:00 UT. EIT CCD bakeout until 2004/07/04 (Sunday).

LASCO C2 and C3 will be in high cadence during the rest of the week: 
C2 at a 12 minute cadence, C3 at the 30 minute cadence.

01:24 UT  E Limb	Loop front with apparently twisted inner structure 
			preceded (surrounded) by a fainter and diffuse front
			slightly ahead and to N moving faster. Both features
			fade in C3.
 
05:48 UT  W Limb	Bright loop front with structured interior. It fades
			throughout C3.

11:36 UT  ES East	Big spray-like front. At 12:48 UT, a brighter and
			ragged front is discernible just above the limb in the
			trailing material. A similar one at 14:24 UT, slightly 
			to N.

	14:48 - 18:48 UT	Telemetry Data Gap.

19:12 UT  S West	Fairly faint front already under development evolves
			as a V-shaped feature (kind of 'reconexion event': 
			starting at 20:57 UT its counterpart is discernible
			falling down). The outward-moving feature fades 
			throughout C3.

20:48 UT  N East	Ragged loop front. It fades throughout C3.

22:00 UT  W Limb	Ragged loop front with an extremely faint and diffuse
			front ahead of it, fading very close to the inner 
			edge of the C3 FOV.

2004/07/02 (Friday)

05:00 UT  E Limb	Wide and diffuse loop front that develops spanning 
			all the way from N to S Pole, surrounds a well defined
			loop front (PA ~ 078 - 148) and a ragged loop front 
			(PA ~ 050 - 083) (measurements on C2 at 06:00 UT).
			
05:24 UT  N Pole	An extremely faint and diffuse front starting over the
			N Pole seems to cover the C2 occultor later during 
			its evolution. It is difficult to discern whether it 
			is related to the previous event. No X-ray events
			reported by the time. 
	
05:48 UT  S West	Faint and diffuse ragged loop front.

	08:10 - 13:50 UT	Temporary DSN Data Gap.
