	1) Coordinated Herschel Rocket and Natural Solar Eclipse Observations

	Sequence: 09.07_Eclipse.tcl, n=5, m=3, p=0, r=0, e=0

	SCI_SPEC: UVCS used a special observation program to support the 
		  natural solar eclipse and was also intended to support 
		  the HERSCHEL rocket flight observations. The program 
		  started with observations of the north coronal hole at 
                  1.9, 2.0 and 2.4 solar radii in H I Ly-alpha. UVCS
		  observations of a streamer above the west limb in 
                  H I Ly-alpha at five roll positions with five heights 
		  from 1.8 to 2.7 solar radii. The second part of the 
		  program observed the west limb streamer in O VI 103.2 nm 
		  at 1.75, 2.45 and 3.5 solar radii. The central roll 
                  position for the streamer observations targeted the 
                  central axis of the streamer. For each observation 
                  the roll positions were adjusted to use the high 
                  resolution portion of the UVCS field of view. The 
                  observation durations were designed to produce both 
                  intensity and profile quality data for both spectral lines.

		  Roll positions are High Resolution corrected for PA=270 deg.
