Kohl: Lead Scientist ---------- Y.-K. Ko: Commander, Planner M. Uzzo: Commander R. Wu Command file: 03.09.18.11:47:33.cmd.log Activity: --------- 1) UVCS Pointing Adjustment and Roll Test Sequence: Manual SCI_SPEC: The UVCS pointing mechanism was adjusted to correct for instrument drift and center the pointing at sun center. The instrument was then rolled to check how SUNX and SUNY were modified.

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=355 degrees.
