Wu Command file: 03.10.07.12:04:27.cmd.log Activity: --------- 1) UVCS in Soft Safe Configuration Sequence: None SCI_SPEC: Following completion of Synoptic for 05 October 2003, UVCS is placed into a soft Safe configuration in preparation for SOHO Momentum Management, Station Keeping, and Roll. Detector High Voltage is ramped down and turned off, OVI Slit is closed from 150 microns to 100 microns, instrument is rolled to 35156 Engineering Units, and Mirror / Occulter is moved to 1.5 Solar Radii with 1.5 mm overocculting. Expected Limit Violation sheets submitted to FOT via SOC for any expected limit violations during this time. Experiment Offpoint Flag is disabled.
