 	2) Observation of High-Latitude Coronal Hole

	Sequence: 01.01_hole4.tcl

	SCI_SPEC: Characterization of a high-latitude coronal hole.
                  Goal is to measure the properties of a high-latitude 
		  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 polar coronal holes.
