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.
