Wu ------------ UVCS Activity: UVCS in Modified Hard Safe Configuration -------------- SOHO Activity: MANEUVER TIMELINE FOR 12 MAY 2009 SK/MM/Roll -------------- Standard Disclaimer: All times are in UT and are estimates. Total Fuel Usage: ~32 grams OCD (offpoint flag, SVM times, ESR flags) due Wednesday 6 May SORR on Thursday 7 May Limit violation sheets for safing due: Friday MONDAY 11 MAY 2009 ------------------ D45 03:20 - 05:55 D54 16:30 - 18:35 D24/D14 23:30-02:10/02:30 SOCs here at 8am UVCS safed on 1 May SVM Reserve Time 16:30 LASCO safes (~30 minutes) at ~17 CDS safes (use TSTOL c_fl_submode_prep, c_fl_shutdoors from Maneuver Prep) at ~17:30 TUESDAY 12 MAY 2009 ------------------- D45 03:45 - 05:55 D24 14:05 - 22:05 SOCs here at 8am SWAN safed by FOT: run n_fl_llockin, go to ESR limit set CELIAS not safing MDI loop opened by FOT with warning ~14:45 Experiment offpoint flag function disabled SK (4 minutes), MM (35 minutes), Roll (26 minutes) Burns should be complete by ~16:45 Experiment offpoint flags enabled for LASCO and MDI MDI loop closed by FOT after asking permission ~19:30 SWAN recovered by FOT (2 hours after last burn): go to nominal limit set, run n_fl_llockout, send n_fl_manrec Submode Change to Submode 6 ~20 (if there is nearly 2 hours of time) NRT: for CDS recovery if crashed during submode change for LASCO recovery (if there is time) EOF Staff: R. Wu: Lead Scientist ---------- 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 February 2009. 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.
