Cranmer: Lead Scientist ---------- R. Wu: Commander D. H. Phillips / Y.-K. Ko: Planner M. Uzzo Command file: 02.02.15.19:02:13.cmd.log Activity: --------- 1) Observation of High-Latitude South Hemisphere Coronal Hole Sequence: 01.06_hole1.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. Roll positions are VL-corrected for PA=215 degrees.
