On-console times are 10:25 am & 7:30 pm. Perform dark current test Mon. Nov. 20 - RAC, TLA. On-console time is 6:30 pm. REAL TIME OBSERVATIONS GMT OBSID ---------------------- ---- ----- 3 fids, 5 stars 1458 1562 Notes from 9 am meeting ------------------------ OPS: Passes 2 over the last day SSR dumps 3 Data loss none Load is good -> 325:05:26 CAPs 679 EPS patches 672 reenable SCS212 next passes 2125 MP: The NOV2000 load is approved. Ken has started the Nov2700 load, to be finished by next Wed. Leonids tonight: peak at 0545 GMT. Chandra is 17 deg. from antiradiant now. at 0330 it'll move to 7 deg.. At 0600 for the CTI it'll be at the antiradiant. There'll be no loss of observations. At 1520 Chandra will maneuvber to 50 deg. from the antiradiant. HRC HV to be ramped down. ACIS radiator: radiator cooling is a tradeoff with momentum management. ACIS team wants to keep protecting. They gave a new requirment that is better for momentum management. S/C: We are all set for the grating moves tomorrow, and the ACA dark current test Monday evening. GOT: We are working with GSFC on the swap to a new PTP (Preliminary TLM Processor?). SOT: Radiation is low. Status of OTG automation software development: A draft of the requirments and design spec was released last Monday and is being reviewed. On Wed. we decided to have a review led by TRW on Dec. 1. This will include Overview Demonstrate how the design meets the req'mts Identify any operational limits Discuss the test plan. ASCDS: Lots. Meetings: Flight Director Board 1:00 next Tues.
