		TUESDAY -- 19 FEB 2008
		----------------------
		D34    00:45 - 07:00
		D63/66 11:45 - 15:20
		D24    16:00 - 00:15

		SUMER already safed: Mon 19 Nov 2007
		UVCS already safed: Mon 11 Feb 2008
		SVM reserve time ~12:00-13:00
		SOCs here 13:00-00:00 
		LASCO safes at ~13:30 UT
		CDS safes at ~14:15 UT
		Use TSTOLs c_fl_submode_prep and c_fl_shutdoors
		CDS removed from ESR flag warning list (Maneuver Prep Script)
		D63/D66 pass ends at 15:20 UT
		D24 begins at 16:00 UT
		SWAN safed by FOT: run n_fl_llockin, go to ESR limit set
		CELIAS does not safe
		MDI loop opened by FOT with warning ~16:25 UT
		Experiment offpoint flag function disabled
		SK/MM: SK (~11 minutes) then MM (~40 minutes)
		Burns should be complete by ~18:20 UT
		Experiment offpoint flags enabled for LASCO and MDI
		MDI loop closed by FOT after asking permission ~19:35 UT
		SWAN recovered by FOT (2 hours after last burn): go to nominal
		limit set, run n_fl_llockout, send n_fl_manrec
		CELIAS has not been safed, no recovery necessary

		[NOTE: SK/MM not performed due to following received via email
		from SOC 20 February 2008): 

		050/1757 (2/19) - D24  124 minute TM loss (~27 minutes 
		unrecoverable (1957-2021)), comm line cut]

		WEDNESDAY -- 20 FEB 2008
		------------------------
		D65     10:30 - 14:45 D/L only
		D66     10:30 - 11:30 (probably too short to do anything and 
				       still in automation)
		D43/D46 00:20 - 02:20 (already in automation)

		No manoeuvre activities.

	Activity:
	---------

	1) UVCS in Modified Hard Safe Configuration

	Sequence: None

	SCI_SPEC: Following completion of Science Observations, UVCS 
		  is placed into a modified Hard Safe configuration in 
		  preparation for the SOHO High Gain Antenna Keyhole 
		  Period of February 2008.

		  OVI and LyA Slits are set to 100 microns, instrument 
		  is rolled to nominal East (35156 Engineering Units).  
		  Detector High Voltage is ramped down and then turned off.  
		  The Mirror is moved to 1.5 Solar Radii with 1.5 mm 
		  overocculting.  UVCS Aperture Door is also closed 708 steps, 
		  Internal Mirror / Occulter Heater set to 100% duty cycle 
		  (64).  
		  		  
		  FOT using ESR Limit Set, TSU Substitution Heater (Circuit 
		  #84) powered on and set to 50% duty cycle.  UVCS removed 
		  from Experiment Offpoint and ESR warning lists for Keyhole.
