Kohl: Lead Scientist ---------- R. Wu: Commander Y.-K. Ko: Planner M. Uzzo Command file: 02.05.10.15:42:48.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=210 degrees. NB: 131/1617 UT D27 antenna went to brake. Lost 8 minutes 53 seconds of unrecoverable TLM and 11 minutes of command ability. DOY 131/1658 UT Received degraded TLM on D27 from 1658 to 2026, cause unknown. Any lost data is unrecoverable.
