Wu: Lead Scientist ---------- M. Uzzo: Commander, Planner Command file: 09.08.13.14:43:37.cmd.log Activity: --------- 1) UVCS in Modified Hard Safe Configuration Sequence: None SCI_SPEC: Following completion of Science Observations, UVCS is placed into a modified Hard Safe configuration in preparation for the SOHO High Gain Antenna Keyhole Period of July/August 2009. OVI and LyA Slits are set to 100 microns, instrument is rolled to nominal East (35156 Engineering Units). Detector High Voltage is ramped down and then turned off. The Mirror is moved to 1.5 Solar Radii with 1.5 mm overocculting. UVCS Aperture Door is also closed 708 steps, Internal Mirror / Occulter Heater set to 100% duty cycle (64). FOT using ESR Limit Set, TSU Substitution Heater (Circuit #84) powered on and set to 50% duty cycle. UVCS removed from Experiment Offpoint and ESR warning lists for Keyhole.

Detector High Voltage remains ramped down and turned off instrument is rolled to nominal East (35156 Engineering Units). The Mirror stays at 1.5 Solar Radii with 1.5 mm overocculting. UVCS Aperture Door is opened at this time, Internal Mirror / Occulter Heater set to 0% duty cycle (255). OVI Detecor Timing and Charge Thresholds set. FOT told to continue to use UVCS ESR Limit Set. FOT component of UVCS recovery, including enabling of the ESR Warning at ? UT and Experiment Offpoint Flags (at, ? UT, and the TSU Substitution Heater (Circuit #84) OFF completed at approximately ? UT UVCS NRT portion of recovery begins at approximately 18:03 UT. Note: Recovery times (below) are approximate.
