Do diagnostics to evaluate grating anomaly. Next observation is OBSID INTA1, CAL-ER 2000:129:22:32, intermediate attitude for OBSID 00682, XTE J1550-564 2000:129:23:00 (TOO). Current pass will extend to 3:06 pm today. Next pass, today, 6:25-7:45 pm EDT. Grating will insert at 6:41 pm.

Last load good till day 129:21:44. Did a CAP 599 for thermal diagnostics. Mission planning: All set to finish the May14 load. Spacecraft eng'ng: during the pass at 0700 GMT the OC noticed that the HETG was not inserted. Andy delogged the TLM: commands fine, load stepped correctly, OTG motion enable flag didn't go. Pot reading of ~80 is normal for retraction. This may be a problem with a bit of bouncing of the grating as it retracts, and the switches sensing it before it completely settles. We plan a series of diagnostic dumps. We will look at the last insert-retract cycle, microswitches, etc. The goal is to see if we are good for the next grating observation. If we can't insert for the TOO, it's a factor of 5 more dose, which is OK. Andy is preparing a CAP that will be reviewed at 10:30 am EDT. Keith Havey suggests that we look at attitude excursions at retraction time to see any possible anomalies. There is no hard stop on retraction. We expect to see some settling, apparent in the spacecraft motion. SOT Lead: proton flux is low and steady. ASCDS: one QL today. The processing was lost on Saturday. CXC MGR: bimonthly tomorrow all day in conf rm, VIPs from office of budget/mgt today ~ 3 pm, Cady Coleman Thurs 10 am. Data ---- On colossus at 1241 GMT.(/dsops/GOT/input), May 8 04:29 2000_128_1902_129_0401_Dump_EM_58323.gz Evaluation of QL data --------------------- The following observations should be available for review. If there is no comment after the entry, it means that there is no record of ascdsops QL processing. If it has been reviewed by SOT Lead, a review evaluation comment is given. If it is in the ascsdops record but not listed as QL processed, the ascdsops comment is given. We still have a rather large backlog.
