	1) Partial Recovery of UVCS to Modified Safe Configuration

	Sequence: 

	SCI_SPEC: UVCS Aperture Door remains closed. UVCS TSU Substitution 
		  Heater (Circuit #84) is turned off.  OVI Detector Power is 
		  turned on.  Spectrometer Heater is set to 50% Duty Cycle
		  (128 Engineering Units), and Mirror Occulter Mechanism
		  Heater is set to 100% Duty Cycle (64 Engineering Units). 
		  
		  Message from SOC received Sunday, 12 July 2009 16:10:34 GMT:
		  
		  SOHO has been in Emergency Sun Reacquisition (ESR) since 
		  approximately 0413 UT today (12 July 2009). The likely 
		  cause of the ESR was spurious CSPAAD triggering.

		  Initial instrument safings and thermal adjustments have been 
		  done. The spacecraft is currently in Coarse Roll Pointing 
		  (CRP) mode, but the spacecraft recovery remains incomplete.

		  Due to downlink-only passes both today and tomorrow, the 
		  recovery activities will cease for today no later than 1650 
		  and continue tomorrow 13 July 2009 as of approximately 1630 
		  UT.
