Ko Command file: 02.10.02.14:37:00.cmd.log 02.10.02.18:17:00.cmd.log Activity: --------- 1) Observation of a North Polar Coronal Hole Sequence: 02.06_hole1.tcl SCI_SPEC: Characterization of a northern coronal hole. Goal is to measure the properties of a 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 non-polar coronal holes. Roll positions are VL-corrected for PA=350 degrees.
