Shift L448. Start at 286:12:00 GMT = 08:00am 12 Oct EDT End 12:00 noon 12 Oct SOT Lead DAS (Times will be given in GMT on day 286. In general times are rough, not precise.) PLAN ---- Continue running load OCT0900D. We are safed for Perigee passage, will do ACIS CTI on egress, then an ACIS-S observation to study dark matter distribution and models of the X-ray halo in NGC 720, obsid 492. Next Comms: 286:14:35 to 15:50 286:21:00 to 22:15 287:04:40 to 05:40 287:15:00 to 16:00 Orbital events: 286:14:24:21.898 EPERIGEE 163 ORBIT PERIGEE 287:22:08:24.329 EAPOGEE 164 ORBIT APOGEE 289:05:51:29.850 EPERIGEE 164 ORBIT PERIGE EVENTS ------ Status at LOS, 286:09:08, was as follows: PCAD MODE = NPNT CONTROL LAW FLAG = NPNT Stars: = 7 FIDS = 0 RA = 26.828 deg DEC = 18.124 deg ROLL = 138.852 deg Format = 2 OBSID = 61887 ACIS CTI SIM FA = -715 SIM TSC = -99615 (HRC-S) HETG = OUT (79.8 deg) LETG = OUT (78.3 deg) HRC-I HV is ON EPHIN Geom = SMAL E1300 = 0.1 LT 10.0 (RADMON P4GM = 78.6 LT 300.

NOTES/ISSUES/PROBLEMS From the 9am status meeting: 3 supports, 4 dumps, first load segment from OCT1600b was uplinked, so onboard loads are good through 290:05:05 Ran the CAP 648b for the routine monthly update of the on-board emphemeris coefficients. Ran CAP 662 to turn off SSR B. The OCT1600b load was approved yesterday. The OCT2300 load, containing the lunar eclipse operations, is in work. Restoration of GRETA from the tape of data recovered from the crashed disk, did not work. The vendor will reship the recovered data and we'll try again. (Difference, if any, in reshiped data is TBD.) Meetings today: 11 am EDT, identification of critical software, action room 2pm EDT, Flight Director CCB, OCC conference room and telephone 405-244-5060, passcode 1159#. 3pm EDT, FOT/MP telecon with CSC on OFLS.
