Cranmer: Lead Scientist ---------- M. Uzzo: Commander, Planner Y.-K. Ko R. Wu Command file: 04.01.09.16:53:08.cmd.log Activity: --------- 1) Coronal Hole Observation / Engineering Study with MCP voltage @ 200 Sequence: 04.01_hole1_230.tcl SCI_SPEC: Examining the possibility of running this observation at grating position 230,000 with MCP voltage at 200. Characterization of an equatorial coronal hole. Goal is to measure the properties of a non-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 polar coronal holes. Roll positions are VL-corrected for PA=280 degrees.
