UVCS MISSION LOG ---------------- Date: 24 January 1997 ----- Last revision: 97/01/27 (Wu) -------------- File Name: 97.01.24.a.log ----------- Compiled by: S. Fineschi ------------ UVCS Activity: OVI line profiles in Polar Coronal Hole -------------- Start of Synoptic for 25 Jan SOHO Activity: -------------- EOF Staff: S. Fineschi (Lead scientist) ---------- R. Wu A. Modigliani Command file: 97.01.24.15:23:01.cmd.log Activity: 1) OVI line profiles in Polar Coronal Hole Sequence: 97.01.24_silvano SCI_SPEC: The purpose of these observations wass to obtain highly accurate profiles of plume and "inter-plume" regions for OVI 1032, OVI 1037, HI 1216, and HI 1025 at 3.0 Ro. However, because of the commanding error (sse NOTE) that has made the procedure run with the OVI slits closed (i.e., 5 um), this observation can be considered a backgroung for the OVI channel.

This has caused the synoptic - loaded in batch queue - to be skipped (see file 97.01.23.a.log). Furthermore, the OVI slits have been closed shut, during the execution of this procedure because the command that was supposed to open the slits before the synoptic, was also in the batch queue, and thus was skipped. The next command, in interactive queue, was a "close OVI slits" again, that, when executed, closed the OVI slits even more.
