Three (3) supports yesterday, all OK. Three supports are scheduled in the next day. - Mission Planning: Kevin working on DEC12 load, looking good. Co-ordinating for SI safing SCS and script testing. SI safing test Monday, DEc 13 from 2:00pm till 8:00pm EST. Reserving 1 hr COMM time Dec 19 for SI safing script testing. Trying to get products out tonight. Ken working DSN requests for out weeks. - Joy Nichols that the data processing for this load (DEC0599) was still running behind due to the fact that this load was not ingested into the archive soon enough. Quick look plots provided for several observations from previous loads. See below. Reported on problems in data processing with thousands of ACA strip files created due to stars blinking in and out of track due to exceeding a bright threshold limit. This is a problem that the data processing system will have to learn to deal with (per Roger and Dan). - SOT Lead report: Disk failure reported on coot. Contacted Dan Rehner/Lisa Paton to get fixed. 2) Chandra's state at AOS 341:1540 was: WAS EXPECTED PCAD MODE = NPNT NPNT CONTROL LAW FLAG = NPNT NPNT Stars: = 4 4 FIDS = 3 3 RA = 163.203353 deg 163.203352 DEC = 57.458786 deg 57.458785 ROLL = 82.479611 deg 82.4796 Format = 1 1 OBSID = 579 579 SIM FA = -715 -716 SIM TSC = -50504 (HRC-I) -50505 HETGA = 80.58 deg (OUT) OUT HETGB = 81.33 deg (OUT) OUT LETGA = 80.58 deg (OUT) OUT LETGB = 79.08 deg (OUT) OUT EPHIN A-leak = 0.4200 B-leak = 0.0640 ACIS = ACIS Workstation fixed.
