Kohl: Lead Scientist ---------- S. Mancuso: Planner, Commander Y.-K. Ko M. Uzzo Command file: 01.04.27.16:23:56.cmd.log Activity: --------- 1) Observation of Mid-Latitude Coronal Hole Sequence: 01.01_hole1a.tcl SCI_SPEC: Characterization of a mid-latitude coronal hole. Goal is to measure the properties of a mid-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=229 degrees.
