P. Miralles: Lead Scientist ---------- R. Wu: Commander Y.-K. Ko: Planner D. Phillips: Planner S. Mancuso M. Uzzo Command file: 01.04.12.15:16:01.cmd.log Activity: --------- 1) Observation of Low-Latitude Coronal Hole Sequence: 01.01_hole1a.tcl SCI_SPEC: Characterization of an Equatorial Coronal Hole. Goal is to measure the properties of a mid-latitude 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.
