	Activity:
	---------

	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.

	OBS_PROG: Primary: Sensitivity
		  Sub Obj: Spatial Coverage

	SCI_OBJ:  Plasma Properties...Proton and Ion Temperatures

	OBJ:      Coronal Hole

	CMP_NUM:  

	Duration: start: 2009.07.10.17:10
		    end: 2009.07.11.16:10

	ONUMs = 25617 (318 exps)   
		25618 (347 exps)

	Instrument configuration:

		- Pointing:  Sun center

                - Spacecraft Roll:  180 Degrees

		- Roll: 352.09 Degrees (50331)

		- Mirror/Occulter:  2.1 Ro
				    1.5 mm overocculting

		- LYA Slit:   100 um
		- OVI Slit:    50 um

		- LYA GRTPOS: 100000
		- OVI GRTPOS: 232100

		- OVI MCP Voltage: 205

	2) OVI Detector Dark Rate Diagnostic

	Sequence: OVI_dark_chk.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.
