Purpose is to investigate faint star acquisition with ACA. CAP tentatively approved pending review of command loads by Rob Cameron. This to be done early afternoon prior to upload and execution. Next COMM period is 238:1750 (1:50pm edt) to 239:0030 (8:30pm EDT). CAP 338 to be done during this COMM AFTER entry into radiation at 238:2000. - COMM periods upcoming are: 238:0740 - 238:1215 238:1750 - 239:0030 239:0900 - 239:1135 239:1630 - 239:2245 240:0400 - 240:0800 240:1455 - 240:1830 - Load P8 has an error in OBSID 1267. Is 3.6Ksec and needs to be 15 ksec. Second part of load P8 being rebuilt now, to pick up at 240:0755 after HETG insertion. Load to be built today for review early tomorrow and uplink tomorrow pm. New P8 load picks up at SAT, 8/27 at 0355 EDT. - HETG insertion is to be done via real time commands (CAP 341 + SAP 8M014). This will be done between 240:0435 and 240:0755. CAP briefed by Keith Havey at meeting. OBSID will be 1098 and ACIS will observe during and after insertion. Insertion will be done in Format 4. Later observation in Format 2. - HRC activation discussed by Mike Juda. Tentative start time will be 242:1330 if COMM period can be extended. Most activities are real time. Will take 1.5 days and will view LMC X-1.
