	1) Modify Hard Safe Configuration

	Sequence: Manual

	SCI_SPEC: On DSN-54 pass the Hard Safe configuration was modified 
		  preparation for the maneuver and 23.5 hour gap during
		  preparation for the SOHO High Gain Antenna Keyhole 
		  Period of March 2006.

		  The OVI and LYA detectors are powered OFF and the
		  Spectrometer Heater duty cycle set to 0% (255).

 		  The FOT use ESR Limit Set, turn on TSU Substitution Heater
		  (Circuit #84) using a 50% duty cycle.  All other settings 
		  remain the same.

	2) 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 March 2006.

                  OVI Slit is set to 100 microns, instrument is rolled to
                  nominal North East (30475 Engineering Units) to protect
                  OVI detector electronics.  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).  Internal
                  Spectrometer Heater is 0% (255).

                  For the second part of the keyhole for the 23.5 hour
                  gap both OVI and LYA detectors are powered OFF.
 
		  FOT use ESR Limit Set, and TSU Substitution Heater
		  (Circuit #84) set to 50% duty cycle while both detectors 
		  are powered OFF. Experiment Offpoint and ESR Flags 
	     	  disabled for Keyhole.
