Total Fuel Usage = 0.1401 kg OCD (offpoint flag, SVM times, ESR flags) due Wednesday SORR on Friday 3 October at 14:30 UT Limit violation sheets for safing due by 19 UT Friday MONDAY -- 06 October 2003 ------------------------- D63/66 1020-1620 UT SOC here at 11 UT LASCO safes at 11 UT UVCS safes at 13 UT, ESR flag stays enabled, door stays open SVM reserve time 14-15 UT CDS safes at 15 UT ESR flag disabled for CDS and LASCO D43 2030-2345 Downlink only station TUESDAY -- 07 October 2003 -------------------------- D63/D66 0700-1600 UT SOC here by 0730 UT VC2, dump SSR, VC2 CELIAS STOF safed by FOT (CEL031007301.DEL) SWAN safed by FOT, remove SWAN from ESR warning flag list MDI loop opened by FOT with warning Experiment offpoint flag function disabled SK/MM - SK burn, MM burns (3 segments), 26 minute roll Burns should be complete by ~1030 UT Experiment offpoint flags enabled for LASCO, MDI, UVCS MDI loop closed by FOT after asking permission SWAN recovered by FOT, return SWAN to ESR warning flag list - 2 hours after last burn, then do recovery load (SWA031002141.DEL) NRT available at ~1330/14 UT UVCS recovery if there is time D34/43 2010-0055 UT CELIAS STOF recovered by FOT - 6 hours after last burn (CEL031007302.DEL) UVCS recovery if not done earlier (~1 hour) CDS dedicated NRT (~1 hour) EOF Staff: M.

Detector High Voltage is then ramped down and turned off, OVI Slit is closed from 150 microns to 100 microns, instrument is rolled to the nominal West (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.
