Gardner: Instrument Operations Scientist ---------- Y.-K. Ko: Commander R. Wu Command file: 02.06.03.18:10:46.cmd.log Activity: --------- 1) UVCS in Door Closed Safe Configuration Sequence: SCI_SPEC: Detector High Voltage ramped down and turned off, UVCS door partially closed (708 steps). Door Closed temperature limit monitoring (by Flight Operations Team) in place. Mirror / Occulter Mechanism heater on at 100% duty cycle (64 Engineering Units). Spectrometer Assembly heater on at 60% duty cycle (128 EU). Commander was phoned at 10:00 UT by FOT console crew and informed that THSUN temperature was out of bounds at 11.67 degrees C (Yellow Low using Door Closed temperature monitoring is 12 degrees C). Commander received permission from Instrument Operations Scientist to tell FOT to ignore limit violations of THSUN until temperature reached 5 degrees C. Notes: 17:59 UT 03 June 2002, Experiment Offpoint Flag enabled. NRT enabled for instrument teams (~18:11 UT).
