Shift L1931. Start at 308:12:00 GMT = 08:00am 03 Nov EST End 10:00am 03 Nov SOT Lead DAS (Times will be given in GMT on day 308.) PLAN ---- Continue running load OCT3104B. Finish ObsID 4473, an ACIS-S/HETG observation of the Orion Nebula Cluster to study magnetic and accretion properties of the pre-main sequence stars as revealed by the high resolution spectra. Then measure ACIS cti and go into perigee passage. No Comm this shift.

EPH temp 98.62 degF NOTES/ISSUES/PROBLEMS Per email from Sabina yesterday, there will be a community briefing to provide preliminary information on the prop line cooling situation, and the implications for pitch angle restrictions to below 150 deg. Friday, November 5 at 11 a.m. EST, in the action room.   Call in number (405) 244-5060 pin # 1159. SEE: http://occwww.cfa.harvard.edu/occweb/web/fot_web/eng/subsystems/prop/PLINE03T_PLINE04T_low_temps.htm From the 9am status meeting: Three supports in the past day, no issues. One load segment uplinked, on-board loads good until 311:20:21. Working two week load, NOV0804. Tried to insert a target deleted from NOV0104 due to bad pitch angle, but doesn't look possible. Products expected later today, possible review but later than 2pm. Ground system wants to work on 3rd string server reboot today. Firewall A cards being replaced, so we can have a hot firewall backup.
