Shift L1299. Start at 41:13:00 GMT = 08:00am 10 Feb EST End 12:00 noon 10 Feb SOT Lead DAS (Times will be given in GMT on day 41.) PLAN ---- Continue running load FEB1003B. Do ACIS-S observations, obsid 4137 of the radio-loud Narrow Line Seyfert I galaxy FIRST J114047+462204, and obsid 4037 of the red, broad-line quasar 2MASS104044+593409, to study the relative X-ray and optical obscuration. Then into perigee passage. Next Comms: 041:1235 to 1335 042:0310 to 0510 042:0755 to 0955 042:1220 to 1420 042:2340 to 0140 043:0420 to 0620 043:1100 to 1300 043:2010 to 2210 044:0600 to 0800 044:1135 to 1235 Orbital events: 2003:040:19:11:16.781 EAPOGEE 485 ORBIT APOGEE 2003:042:02:56:01.915 EPERIGEE 485 ORBIT PERIGEE 2003:043:10:39:49.530 EAPOGEE 486 ORBIT APOGEE EVENTS ------ Status at LOS, 041:13:34, was as follows: PCAD MODE = NPNT CONTROL LAW FLAG = NPNT Stars: = 5 FIDS = 3 RA = 175.231 deg Dec = 46.369 deg ROLL = 130.071 deg Format = 2 OBSID = 4137 FIRST J114047+462204 SIM FA = -467 SIM TSC = 75623 (ACIS-S) HETG = OUT (79.46 deg) LETG = OUT (77.96 deg) HRC-I HV is ON EPHIN Geom = LARG E1300 = 0.0 LT 10.0 (RADMON P4GM = 0.0 LT 300.

NOTES/ISSUES/PROBLEMS From the 9am status meeting: 10 contacts over the weekend. Two load segments uplinked, onboard loads good through 045:14:35. During the 040/1110-1310 DSS-16 support, two commands were aborted by the ground station command system, but then spontaneously transmitted to Chandra after the station rebooted. This did not cause a problem itself, but it is potentially of great concern if the ground station autonomously can send commands at a time which the OCC does not expect. This situation will be investigated. One eclipse over the weekend, temperatures and voltages were all nominal. Last eclipse of the current season will be about 0540 tomorrow. FEB1703A products expected out this morning for a load review at 2pm today. There will be a project-wide telecon on the MUPS thruster situation at 2:30--5:30pm, EST, tomorrow. Use 405-244-5060, #1165. Presentation materials are expected to be circulated tomorrow morning. We noted ACIS warming up by about 1/2 deg C to -119.2, during the 12:35-13:35 contact, during obsid 4137.
