	1) North Polar Coronal Hole Study

	Sequence: 09.07_hole.tcl, n = 8, m = 1, p = 0, r = 1, e = 0

	SCI_SPEC: Characterization of a polar coronal hole.
		  Goal is to measure the properties of a polar
		  coronal hole. In particular we are interested in the 
		  coronal conditions (intensities and line widths for 
		  HI Ly-alpha and OVI 1032/1037) as a function of height 
		  and latitude. We will compare these properties with 
		  the ones found in non-polar coronal holes.

		  Roll positions are VL-corrected for PA=0 degrees.

	2) UVCS in Safe Mode Due to SOHO ESR

	Sequence: 

	SCI_SPEC: UVCS Aperture Door is closed, and Detector Power is turned
		  off.  UVCS TSU Substitution Heater (Circuit #84) on.

		  The ESR is believed to have been triggered by the CSPAAD 
		  (Coarse Sun Pointing Attitude Anomaly Detector).  
		  
		  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.
