	1) Recover UVCS from Soft Safe Configuration

	Sequence: Manual

	SCI_SPEC: Several X-Class Solar Flares from Active Region NOAA 10720
		  have resulted in elevated energetic proton flux.  The 
		  decision was made to place UVCS into a soft safe 
		  configuration although proton flux had not reached a level
		  where UVCS would normally safe.  This was due to a gap in
		  DSN coverage.  Proton flux was still increasing at the time
		  the decision was made to safe.
		  
		  OVI detector High Voltage is turned on and ramped up, 
		  UVCS is configured for resumption of science.
