Note LETG retraction Thursday, Jan. 25 at 5:30 am EST. REAL TIME OBSERVATIONS GMT OBSID ---------------------- ---- ----- (none) Notes from 9 am meeting ------------------------ OPS: Passes 3 over the last day(s) Data loss none Load is good -> 026:09:30 CAPs none next passes 1900,0500 MP: The load review for JAN2901 load was completed yesterday. The Feb05 load ORs are being worked. OFLS 9.1 will be split into 9.1 and 9.2. 9.2 will have the momentum monitoring function, and will be delivered about end of March. 9.1, containing all the other mods, is delivered to OCC. Test plans are being reviewed. Testing will start next week and last 4-6 weeks. S/C: We will execute CAP 690B to retract LETG this Thursday, day 025 at 10:30-11:30 GMT (5:30 AM EST). The CAP was reviewed this morning, and will be approved by the flight director as soon as the new deadman command load AA_DEAD45193.CLD is approved and installed in the ODB, probably this morning.

There is also a problem with Twinkie, which supplies data for engineering trending & backlogged TLM. It intermittently becomes unavailable. The systems people are investigating. SOT: Radiation is high and decreasing. ASCDS: One QL. Tomorrow morning we plan no QL data for the rest of the week. This is because of a hardware swap that will also mean losing the GOT's dump disk and no reception of R/T data. Joy is working with the GOT to find a way to receive R/T. ********************************************************** If anyone needs QL data later this week, please page Joy at 1-888-849-7468, on a 24 hr basis! ********************************************************** Data ---- On colossus at 1531 GMT.(/dsops/GOT/input), - Jan 23 08:04 2001_023_0048_023_0527_Dump_EM_75311.gz Evaluation of QL data --------------------- OBSID Target SI SOT Eval. ----- ------ ------ ------- 2186 H1821+643 ACIS-S/LETG OK This is a partial.
