SOT Shift Report Shift M151 Duration: 21 Dec 1999 15:00 EST - 21 Dec 1999 18:00 EST 21 Dec 1999 20:00 GMT - 21 Dec 1999 23:00 GMT SOT Lead: Tom Aldcroft Spacecraft/Aspect: FOT/Science Liason: HRC: ACIS: ======================================== Plan ---- Continue with load DEC1799: Obsid 1412 CEN A HRC-I Obsid 749 RX J0822-4300 HRC-I Events ------ 22:11 AOS on DSS-42 23:08 LOS Notes/Issues/Problems --------------------- ACA integration time was left at the ACA default value 0.704 sec after continuous dither testing Monday. Eric Martin and I wrote CAP 538 to upload a baselined command load which sets the integration time to the normal value of 1.696 sec. This CAP was approved and will be done during the next Comm pass starting at 00:40 EST tonight. I plan to contact the SOC by phone and monitor realtime telemetry from home. Snapshot was showing all zeros while LOS. During comm it updated and looks mostly fine, but otherwise it should be showing the last available values. Also, the integrated ACE flux (F_ACE) on the snapshot is 0.0. David Morris is checking into this. Snapshot -------- Snapshot shows current configuration during manuever from CEN A to RX J0822-4300. SIM is within one step of commanded position.
