	2) Place UVCS in Modified Hard Safe Configuration

	Sequence: Manual

	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 September 2006.

		  OVI and LyA Slits are set to 100 and 75 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).
		  
		  UVCS removed from ESR and Experiment Offpoint Warning list
		  at approximately 17:55 and 17:59 UT, respectively.  TSU 
		  Substitution Heater (Circuit #84) turned on at approximately 
		  18:01 UT.

		  FOT using ESR Limit Set, Substitution Heater (Circuit #84) 
		  set to 50% duty cycle.

	3) 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 September 2006.

		  OVI and LyA Slits are set to 100 and 75 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.
