	Activity:
	---------
	1) North Coronal Hole Weekly Study (2.0 Ro)
	
	Sequence: HoleOVIweek.tcl

	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.

	OBJ:      Coronal Hole

	2) Coronal Hole Weekly Study (OVI Detector Dark Rate Diagnostic)

	Sequence: HoleOVIweek.tcl

	SCI_SPEC: Determine Dark count rate for OVI detector. Instrument 
		  rolled to coronal hole, 5.0 Ro with 0.8 mm exposed mirror. 
		  Script engages OVI filter and then disengages it at end.
