Detector High Voltage remains ramped down and turned off. Instrument is rolled to the nominal East (35156 Engineering Units), and Mirror / Occulter is set at 1.5 Solar Radii with 1.5 mm overocculting. UVCS Aperture Door is open. Internal Mirror / Occulter Heater set to 0% duty cycle. FOT told to continue to use UVCS ESR Limit Table. Expected Limit Violation sheets submitted to FOT via SOC for any expected limit violations during this time. FOT component of UVCS recovery, including enabling of the ESR Warning at 16:19 UT and Experiment Offpoint Flags (at, 16:23 UT, and the TSU Substitution Heater (Circuit #84) OFF completed at 16:27 UT OBS_PROG: SCI_OBJ: OBJ: CMP_NAME: CMP_NUM: Duration: start: 2008.02.28.17:00 end: 2008.02.28.20:26 ONUMs = 24075 Instrument configuration: - Pointing: Sun center - Spacecraft Roll: 0 Degrees - Roll: 90 Degrees (35156) - Mirror/Occulter: 1.5 Ro 1.5 mm overocculting - LYA Slit: 100 um - OVI Slit: 100 um - LYA GRTPOS: 100000 - OVI GRTPOS: 210000 - LYA HIGH VOLTAGE RAMPED DOWN AND POWERED OFF - OVI HIGH VOLTAGE RAMPED DOWN AND POWERED OFF - VLD HIGH VOLTAGE RAMPED DOWN AND POWERED OFF - OVI DETECTOR POWERED OFF - VLD DETECTOR POWERED OFF - LYA mask: LYA_303_8x2 in slot 3 Fits Files: 2) UVCS Recovery from Soft Safe Configuration Sequence: Manual SCI_SPEC: Completion of recovery of UVCS from soft safe configuration.
