Wu ------------ UVCS Activity: Mid-latitude Coronal Hole Study for 23 - 24 July 2001 -------------- Mid-latitude Coronal Hole Study for 24 July 2001 Mini-Synoptic for 24 July 2001 SOHO Activity: -------------- EOF Staff: M. P. Miralles: Lead Scientist ---------- R. Wu: Commander M. Uzzo: Planner Command file: 01.07.21.15:43:33.cmd.log Activity: --------- 1) Observation of High-Latitude Coronal Hole Sequence: 01.06_hole1.tcl SCI_SPEC: Characterization of a mid-latitude 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. Roll positions are VL-corrected for PA=230 degrees.
