Uzzo Command file: 02.04.11.16:50:43.cmd.log 02.04.12.12:54:23.cmd.log Activity: --------- 1) Observation of the High Latitude Southern Coronal Hole Sequence: 01.06_hole1.tcl SCI_SPEC: Characterization of the high-latitude southern coronal hole. Goal is to measure the properties of these non-polar coronal holes. 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 the polar coronal holes. Roll positions are VL-corrected for PA=228 degrees.
