Kohl: Lead Scientist ---------- R. Wu: Commander Y.-K. Ko: Planner M. Uzzo Command file: 03.04.11.15:43:30.cmd.log Activity: --------- 1) Observation of the North Polar Coronal Hole Sequence: 02.12_hole1.tcl SCI_SPEC: Characterization of the 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=357 degrees.
