Start at 068:13:00 GMT = 08:00am 09 Mar EST End 10:00am 09 Mar SOT Lead DAS (Times will be given in GMT on day 068.) PLAN ---- Continue running load MAR0611B. Go through perigee passage. Then do obsid 12927, an ACIS-I observation of the AKARI-NEP-Deep Field, to use the X-ray data to classify AGN at redshifts ~1 which have been found in infrared observations, and search for Compton-thick AGN. Then do obsid 12838, an ACIS-I observation of the Swift-INTEGRAL hard X-ray (SIX) field to find an optical counterpart and measure X-ray absorption. Then do obsid 13180, an HRC-I GTO obsrvation of M31 as part of a monitoring program to measure light curves of super-soft sources to constrain the envelopes and white dwarf masses, and to monitor variability of 200 X-ray sources in the center of M31. NOTES/ISSUES/PROBLEMS --------------------- I0/FEP5 did not produce any events during OBSID 12934 on day 66. - the level 0 events file for I0/FEP5 has no events - the bias file for I0/FEP5 for this run appears nominal - the level 0 exposure records have no threshold crossings or events sent for I0/FEP5 for this run Ran CAP 1175 to diagnose ACIS anomaly. I0 and FEP5 looked nominal at 06:15 pass. As reported in H4248 all test results were nominal and it was concluded that the anomaly was a temporary occurence. From the 9am status meeting: Three supports completed. DSS-27 lost telemetry for ~10 min but reset antenna display and completed requirements. CAP 1175 to diagnose ACIS I0/FEP5 anomaly ran smoothly. MAR1411 products out today for review tomorrow. Some OBA temps just over yellow limits briefly, at end of a long pointing at unfavorable attitude. No concern. ACE P3 soft proton rates have been in the few 100's 200 particles/cm2-s-ster-MeV over the past day. They seem to be increasing just at this time (1400) which may be the CME from Mar 6 hitting the Earth's environment. This is a concern and will need to be watched today. >Thanks to Joy for finding and alerting the I0/FEP5 issue, and to Paul >Plucinsky and the ACIS team for investigating quickly and preparing >and executing a CAP which indicated ACIS is currently normal, and to >the FOT for their support of the CAP process.
