UVCS MISSION LOG ---------------- Date: 09 December 2002 ----- Last revision: 12 December 2002 (Wu) -------------- File Name: 2002.12.10.a.log ----------- Compiled by: M. Uzzo ------------ UVCS Activity: Equatorial Coronal Hole Study for 10 - 11 December 2002 -------------- Equatorial Coronal Hole Study for 11 December 2002 Note: Science is a bit behind schedule due in part to unexpected safing of UVCS instrument SOHO Activity: -------------- EOF Staff: J. Kohl: Lead Scientist ---------- M. Uzzo: Commander, Planner R. Wu Command file: 02.12.09.14:14:48.cmd.log Activity: --------- 1) Observation of an Equatorial Coronal Hole Sequence: 02.12_hole1.tcl SCI_SPEC: 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=257 degrees.
