SOT Shift Report Shift M46 Duration: 05 Sep 1999 14:00 EDT - 05 Sep 1999 22:00 EDT 05 Sep 1999 18:00 GMT - 06 Sep 1999 02:00 GMT SOT Lead: PPP Spacecraft/Aspect: EM FOT/Science Liason: HRC: SSM,GA,JHC,MJ ACIS: HETG: CC LETG: BB,PP ======================================== Status: ------- - HRC was observing CAS-A during OBSID 174 at the beginning of shift. We had a two hour contact from 16:00-18:00 GMT but no one was here from the HRC team to show us a pretty picture of Cas-A. One of the HRC displays showed a total count. Tom called Gerry on the previous shift to verify that the observed count rates were within acceptable limits. - ACIS is in the midst of a 94ks Event Histogram run on the modified S array. Data looks nominal, but there is precious little one can discern in FMT 1. This will be the longest ACIS run executed during flight to date. Plan ---- Insert LETG for the first time, starting sometime after GMT 18:00 !!!!! - execute SAP 8M010 LETG LL1A RELEAS - execute SAP 8M012 LETG LL2A RELEASE - CAP 381 PCAD Safing and Grating select - execute SAP 8M016 LETG DEPLOY We have a 5.5 hr realtime contact starting at GMT 18:00 Continue with HRC-S/LETG observations of Capella 18:00 LOS at start of shift 22:00 AOS on Madrid, only a few minutes late today 22:15 briefing on the loops of the necessary procedures 22:45 HRC HV up, Capella is visible in realtime 23:00 SAP 8M010, apparently one of the loads is wrong, the procedure will need to be redlined 23:14 switch to FMT 4 for gratings insertion (sorry ACIS) 23:22 launch lock 1 released 23:30 SAP 8M012, started 23:37 launch lock 2 released 23:40 HRC announces that they wish to execute CAP 352A 23:41 switch to FMT 1 23:53 switch to FMT 2 to clear the ACIS Event Buffer 249:00:00 00:00 start SAP 8M016 00:10 switch back to FMT 4 00:11 execute CAP 381 00:19 start LETG insertion 00:24 switch to FMT 1 00:26 change to OBSID 62435 00:32 execute CAP 382, to start turning on HRC 00:38 FIRST HRC IMAGE OF THE DISPERSED IMAGE !!! YIPPEE !!!! Jeremy says: " mmmmmmmmmn, there's nothing bright around 71 A" 02:00 Everyone is smiling, food and photons VACMON = OFF Altitude GMT 19:00 = 126,000 km NOTES/ISSUES/PROBLEMS - the SDS Duty scientist (Jonathan) expressed a concern that the as-run timeline of events is difficult to determine from the existing records. He suggested that more detail in the SOT shift reports could help alleviate this problem. - no time to waste, working with Jan on ORs and ERs for P12 load
