Shift M14 (B13-A14) Start at 1999:216:18:00:00 GMT = 1999 Aug 4 2:00pm EDT End 10:00pm EDT SOT Lead/FP Sci DAS Spac/Aspect RAC FOT/Sci liaison AN HRC MVZ ACIS YB,BF,ES,EB (Times will be given in GMT on day 216. In general times are rough, not precise.) Plan ---- HRC checkout activities will be postponed. ACIS internal calibration source. Run 18 hours, compare with pre-IPS 4 burn to search for trace of contamination on optical blocking filter. SSR playback. Events ------ 18:12 Run SAP 61082 for ACIS internal Cal. 18:23 Change to format 2. 18:45 OBSID change 62729. plan 3 hour run. 18:53 SSR playback complete. 22:00 orbit update reported. 22:07 ACIS ends science run. 22:07 Uplink OBSID 62728 for next internal cal run. plan 3 hour run. At about 01:10 ACIS starts new run without changing OBSID 01:27 Set OBSID 62727. Restart the ACIS internal cal measurement. 22:25 Lose fid light in slot 6. Presumed cosmic ray. run CAP 129 to recover at 22:30. This was the faintest fid light. 00:47 shift change B13 to A14. Notes/Issues/Problems --------------------- Results from successful IPS-4 burn, new perigee is 5be,689 km expected. Update is apogee is 139,193.3km, perigee height 5649.5 km, period is 61:07:18.6. This is the 5 hour preliminary update, at 22:00. There was discussion about how the ACA real time data, VC #2, would pass to the CXC. Upshot is that we can get the IDR file which JPL ftp's, and this is sufficient for DOSS to evaluate the results. The CXC may still want a NRT-like file, which supposedly isn't produced, but we are looking at how it can be created from the IDR.
