Points Of Interest

Upcoming Operations:

- Keyhole # 7: 2004/12/13 - 2004/12/29

- EIT will get pre-bake cals Saturday 2004/12/11 between 15:00-18:00 UT and 
  start the bakeout shortly thereafter. The bakeout end will be on 2004/12/28
  at 10:00 UT. Therefore, no EIT images during that period.

- During the Keyhole, LASCO will observe with DSN gap recording availability
  thanks to the FOT and the SOCs hard work. C2 and C3 will observe at a 
  standard synoptic plan of C2 at 20 minute cadence and C3 at the 30 minute
  cadence with the daily pB and flat field images.

SOHO Telemetry Submode is in Submode 5.

2004/12/09 (Thursday)

  . SOHO Telemetry lost at 21:58 UT on 2004/12/08 (Wednesday).
  . Telemetry recovered in low rate at 22:12 UT on 12/08. Spacecraft in ESR
    (Emergency Sun Reacquisition Mode) when telemetry recovered. 
  . As part of nominal recovery SOHO entered CRP mode (Coarse Roll Pointing) 
    at 04:44 UT.
  . Recovery performed during the day.

Therefore:
	
 	No LASCO images since 21:50 UT on 2004/12/08 (C2 time).  
	Last EIT 195 image taken at 21:36 UT on 2004/12/08.

2004/12/10 (Friday)

	Beginning at 00:48 UT EIT plan was uploaded and starts imaging in
	Submode 5, half-res 195A CME watch at a standard 12 minute cadence 
	with synoptics at the usual spots. 

	No LASCO Observations. LASCO doors closed after ESR of 12/8 @ 21:58 UT.
	LASCO will remain idle till 2004/12/11 (Saturday) @ ~15:00 UT
