P. Miralles: Lead Scientist ---------- Y.-K. Ko: Commander, Planner M. Uzzo R. Wu Command file: 03.01.24.15:07:35.cmd.log Activity: --------- 1) Observation of the Low Latitude Coronal Hole Sequence: 02.12_hole1.tcl SCI_SPEC: Characterization of a low latitude 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=270 degrees.
