Cranmer: Lead Scientist ---------- R. Wu: Commander M. Uzzo: Planner Y.-K. Ko Command file: 01.12.17.19:26:45.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=220 degrees.
