SOT Shift Report 2005-07-27 L2197 Duration: 27 Jul 2005 08:30 EDT - 27 Jul 2005 09:30 EDT 27 Jul 2005 12:30 GMT - 27 Jul 2005 13:30 GMT SOT Lead: Tom Aldcroft ======================================== Plan ---- Continue with JUL2605C load: Carry out simultaneous Gamma-Ray to Sub-Millimeter Monitoring of Sgr A*; then continue observing the X-ray emission from the corona of the powerful, nearby (z=0.02) radio galaxy 3C 442A; then observe SDSSJ0005-0006 as part of a survey of very high redshift quasars; then into perigee: 05951 Sgr A* 2005:208:19:34:00.000 45.0 ACIS-I NONE 06353 3C 442A 2005:209:08:53:31.851 14.0 ACIS-I NONE 05617 SDSS J0005-0006 2005:209:13:14:51.851 17.2 ACIS-S NONE T_E25 CAL-ER (59527) 2005:209:18:36:51.602 8.5 -- -- T_X26 CAL-ER (59526) 2005:210:09:36:05.943 10.0 -- -- Events ------ 11:55 AOS on DSS-54 12:55 LOS Notes from 9am meeting ---------------------- Ops: In Radiation Zone NO Current SI ACIS-I Grating NONE Observation ID 05635 Target 3C 442A Altitude 115.3 kkm Asc Radmon Disable 209/18:11z Next Radiation Zone 209/20:59z to 210/09:36z MP: - AUG0105A products out for review. The time of the review is TDB because of the simulation activities today. Email will be sent out. Engineering: - The ACIS power supply limit violations mentioned yesterday are expected given the warm (-100C) CTI measurement. Without state-dependent limits we probably need to expect violations during future such tests. - Safe mode simulation continuing today Radiation: - A long-duration M3 class flare occurred around 209/04:00z. At the 11:55 pass this morning the E1300 rate went above the RadMon limit for 2 cycles but then went down. At the end of the pass it was at 6.9 (vs. 10.0 limit). - Solar Activity Forecast: Solar activity is expected to be very low to low. A chance for an isolated C-class event is possible from Region 791. - Geophysical Activity Forecast: The geomagnetic field is expected to be quiet to unsettled with isolated active conditions possible. These effects are possible as a recurrent coronal hole high speed solar wind stream moves into geoeffective positio CXC DS ops: - All data processing is stopped for reasons that are being investigated. R/T data flow is nominal.
