Wu: Lead Scientist ---------- Y.-K. Ko M. Uzzo Command file: No Commanding 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 August - September 2007. 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.
