UVCS MISSION LOG ---------------- Date: 13 February 2010 ----- Last revision: 05 March 2010 (RR) -------------- File Name: 2010.02.13.a.log ---------- Compiled by: R. Rosati ------------ UVCS Activity: UVCS in Soft Safe Configuration for Keyhole Period -------------- SOHO Activity: -------------- EOF Staff: J. Kohl: Lead Scientist ---------- R. Rosati: Commander, Planner Command file: No Commanding Activity: --------- 1) UVCS in Soft Safe Configuration Sequence: None SCI_SPEC: Following completion of Science Observations, UVCS is placed into a soft safe configuration in preparation for the SOHO High Gain Antenna Keyhole Period of January/ February 2010. OVI slit is set to 50 microns and LyA to 100 microns, instrument roll is left at nominal North (51551 Engineering Units). Instrument roll will be nominal South following keyhole. OVI Detector High Voltage is ramped down and then turned off. LyA Detector was already off.
