P. Miralles: Lead Scientist --------- Y.-K. Ko: Commander, Planner M. Uzzo R. Wu Command file: 04.08.31.17:16:31.cmd.log Activity: --------- 1) North Coronal Hole Observation Sequence: 04.08_hole1LyA.tcl SCI_SPEC: Characterization of a north polar 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=355 degrees.
