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). UVCS removed from ESR Warning and Experiment Offpoint list at approximately 19:06 and 19:09 UT, respectively. TSU Substitution Heater (Circuit #84) turned on at approximately 19:14 UT. FOT using ESR Limit Set, Substitution Heater (Circuit #84) set to 50% duty cycle.
