Kohl: Lead Scientist ---------- R. Wu: Commander Y.-K. Ko: Planner Command file: 02.12.23.22:04:00.cmd.log Activity: --------- 1) Observation of an Equatorial Coronal Hole Sequence: 02.12_hole1.tcl SCI_SPEC: Characterization of an equatorial coronal hole. Goal is to measure the properties of a non-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 polar coronal holes. Roll positions are VL-corrected for PA=230 degrees.
