	1) UVCS in Modified Hard Safe Configuration

	Sequence: None

	SCI_SPEC: Following completion of Coronal Jets Study for 24 June 2003, 
		  UVCS is placed into a modified Hard Safe configuration in 
		  preparation for the SOHO HGA Blackout Period.  

		  Detector High Voltage is then ramped down and turned off, 
		  OVI Slit is closed from 150 microns to 100 microns, 
		  instrument is rolled to the nominal East (35156 Engineering 
		  Units), and Mirror / Occulter 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.  Internal Spectrometer Heater is not turned
		  on.  In addition to "traditional" Hard Safe configuration,
		  UVCS Detector Power is turned off.
		  
		  FOT Monitoring UVCS using ESR Limit Table, TSU Substitution 
		  Heater (Circuit #84) and set duty cycle to 60%. 

		  Expected Limit Violation sheets submitted to FOT via SOC
		  for any expected limit violations during this time.  FOT
		  told to ignore USDR = MOVING condition, but to notify UVCS
		  representative should this condition change for more than
		  two minutes.

		  Experiment Offpoint, and ESR Flags are disabled.
