Miralles: Lead Scientist ---------- M. Uzzo: Commander, Planner R. Wu Command file: 03.04.18.11:55:32.cmd.log Activity: --------- 1) Observation of a Mid-Latitude Southern Coronal Hole Sequence: 02.12_hole1.tcl SCI_SPEC: Characterization of a mid-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=225 degrees.
