Kohl: Lead Scientist ---------- Y.-K. Ko: Commander, Planner M. Uzzo R. Wu Command file: 02.12.20.18:51:29.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=257 degrees.
