Three (3) supports yesterday, 3 SSR dumps, all OK Three supports are scheduled in the next day. - Mission Planning: Kevin working on DEC12 load. Having trouble scheduling the second orbit, which includes the SI safing test. There will be a training session on the off-line system today at 1:00pm. - Wallace Jackson reported that the battery glitch counter flight note will be out today. - Joy Nichols that data processing for the current load (DEC0599) was now underway. Two quick-look plots were presented, OBSID's 910 and 316 (see below) A meeting will be held next week to discuss the too-bright guide star issue. - SOT Lead report: Failed disk on coot turned out to be a bad SCSI connection. We have lost data from day 333 to today (11:30am). Looks OK so far today. Also did a complete backup of data on /tlmdata. Telecon on 4 vs. 6 wheel operation is planned for Dec 16 at 11:00am EST. Meet-me number will be used (don't know it yet). 3) Chandra's state at AOS 342:1600 was: WAS EXPECTED PCAD MODE = NPNT NPNT CONTROL LAW FLAG = NPNT NPNT Stars: = 3 4 FIDS = 3 3 RA = 163.208222 deg 163.204434 DEC = 57.457740 deg 57.459153 ROLL = 84.059530 deg 84.0635 Format = 1 1 OBSID = 1483 1483 SIM FA = -715 -716 SIM TSC = -50505 (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 = 0.3640 B-leak = 0.0560 ACIS = HRC IM PS = ON IM Top Step = 77 IM Bot Step = 89 Shield 1 HV = OFF Shield 2 HV = ON Shield 2 HV step = 8 VE Rate 1 = ~40 VE Rate 2 = ~50 Shield Rate 1 = ~4700 Shield Rate 2 = ~4700 4) Quick Look Data Plots: - Following plots were examined and looked OK: OBSID Target Instrument Comments 910 RX J1159+5531 ACIS-I OK 316 NGC 5128 ACIS-I OK
