Shift L1488. Start at 230:12:00 GMT = 08:00am 18 Aug EDT End 10:30am 18 Aug SOT Lead DAS (Times will be given in GMT on day 230.) PLAN ---- Running load AUG1803B. Finish obsid 4207, ACIS-S observation of the compact group of spiral galaxies HCG 80, to search for intragroup gas. Then do obsid 5195, ACIS-S observation of the high redshift, luminous, relaxed cluster of galaxies MACS1423.8+2404, to constrain the cosmological constant.

ACIS focal plane temperature -119.7 NOTES/ISSUES/PROBLEMS From the 9am status meeting: Seven supports over the weekend. DSS-66 had poor data quality. The pointers were reset and part of the poor quality data was overwritten, but then we commanded to SSR-B to allow recovery. (Data quality was ~98.3%, amount of unrecoverable data should be < .5% of the original dump.) Note that automatic processing will be held up until the data is recovered, as it must proceed in strict time order sequence. CAP688AJ was run for the August Ephemeris update. AUG2503 scheduling is in work. Products expected out tomorrow for a review on Wednesday. ASVT disassembly is to start late today or tomorrow, for shipment on Thursday and delivery here next Monday. Delta Pre-ship Readiness Review will be held via telecon this afternoon at 4pm EDT. The HRMA strut-to-strut diametral gradient has increased since IRU-A was turned off. This is expected due to IRU-B putting a more asymmetric heat load compared to either IRU-A or both IRU's together. There will be a telecon with Kodak, Keith Havey, at 3:30pm today on 405-244-5060 1159# to review the data. This is not expected to be a concern. NASA/MSFC quarterly review of operations will take place tomorrow in the conference room, 8:30am EDT to 5pm. Wednesday will be programatic discussions.
