SOT Shift Report 2004-10-19 L1916 Duration: 19 Oct 2004 08:30 EDT - 19 Oct 2004 10:00 EDT 19 Oct 2004 12:30 GMT - 19 Oct 2004 14:00 GMT SOT Lead: Tom Aldcroft ======================================== Plan ---- Continue with OCT1804B load: study the time variability of the central object in RCW103; then explore the nature of the INTEGRAL transient IGR J18410; then study the physics of accretion flows in ultra-low luminosity AGNs; then back to Abell 426: 04599 RCW103 2004:293:13:20:42.457 5.0 ACIS-I NONE 04560 IGR J18410-0535 2004:293:15:12:58.467 10.0 ACIS-S HETG I4692 CAL-ER (59998) 2004:293:18:49:41.388 0.0 -- -- 04692 NGC 3384 2004:293:19:18:37.988 10.0 ACIS-S NONE 06145 Abell 426 2004:293:22:42:28.690 86.0 ACIS-S NONE Events ------ No comm this pass Notes/Issues/Problems --------------------- Ops: In Radiation Zone NO Current SI Grating NONE Observation ID None, Finished 59999 Target None, Finished CTI Altitude 61.4 kkm Asc Radmon Disable 295/12:14z Next Radiation Zone 295/15:31z to 296/02:31z - Experiencing problems with the command database. During the last pass could not send command to turn off transmitter (but no operational impact). Could not uplink load segment. Ground team working to investigate problem, which appears related to a RAID controller card. MP: - The obsid for CAL-ERs just went below 60000. Check your codes for this Chandra "60K" issue - OCT2504A products in work, should be out late today or early tomorrow. Engineering: - Another P4 prop line limit violation seen. An anomaly investigation web page has been created, accessible via: http://occwww.cfa.harvard.edu/occweb/web/fot_web/eng/subsystems/prop/ Radiation: - Radiation continues to be very low, but a new region is appearing around the Sun eastern limb which may be active DSops: - Abell 426 file sizes are all (just slightly) below the limit of 1.9 Gb, so no special processing is expected Other: - There was an unexpected indication of a red limit violation for PCADMODE and RadMon in the SOT Chandra snapshot. This is a processing issue that is being investigated.
