REAL TIME OBSERVATIONS GMT OBSID ----------------------------------------------------------------- 0 fids, 8 stars 1338 61467 Notes from 9 am meeting ------------------------ OPS: Passes 2 over the last day(s) Dumps current Data loss none Load is good -> 268/0550 CAPs none Next passes 0000, 0630 MP: SEP24C approved. The OCT01 load is being worked. We've received the OR/ER lists for OCT08. S/C: Dan Shropshire will be in later today, and stay for the lunar observation late tonight. On day 262 there was a 100" excursion on a large maneuver caused by poor star data ->poor pointing->poor gyro bias calculation. On an unrelated note, we are still working on completing the ASVT update needed so we can do the gyro scale factor update. We met with the ACIS team; they'd like to put new limit data into the P008 database. Reno has added thermal limits based on examining trending data. We will develop two sets of limits: health & safety, and instrument quality. We are also planning to develop a procedure for revising & reviewing the database. GOT: The TLM feed to psicop is done. OFLS1 has been rebooted. ONLS 3.8.1 is installed on the third string. Lockheed is moving their MSFC installation from the "trade zone" building to the HOSC, starting today, and planning finish by 1 Oct. In the interim, CSC won't build software, and Lockheed will be down, including some email. No impact expected. DATA: - SOT: Proton flux is low. A full halo CME occurred on 18 Sep. It may hit earth late today. Another CME on 20 Sept. could affect us on ~23 Sept. MEETINGS -------- ACIS telecon Monday, 4 pm.
