Shift L1323. Start at 65:13:00 GMT = 08:00am 06 Mar EST End 10.00am 06 Mar SOT Lead DAS (Times will be given in GMT on day 65.) PLAN ---- Continue running load MAR0303D. Measure ACIS-CTI before and after perigee passage, then obsid 3728, which is a long ACIS-S/HETG GTO observation of the weak-lined T Tauri star, TV Crt (HD98800), to study a young stellar corona. Next Comms: 065:2250 to 0050 066:0600 to 0750 066:1045 to 1245 066:2315 to 0115 067:1000 to 1100 067:2250 to 0050 068:0600 to 0800 068:1240 to 1420 068:2010 to 2210 Orbital events: 2003:065:22:03:27.568 EPERIGEE 494 ORBIT PERIGEE 2003:067:05:47:48.065 EAPOGEE 495 ORBIT APOGEE 2003:068:13:32:00.814 EPERIGEE 495 ORBIT PERIGEE 2003:071:05:00:49.346 EPERIGEE 496 ORBIT PERIGEE 2003:072:12:44:20.153 EAPOGEE 497 ORBIT APOGEE 2003:073:20:29:10.975 EPERIGEE 497 ORBIT PERIGEE 2003:075:04:12:14.277 EAPOGEE 498 ORBIT APOGEE EVENTS ------ Status at LOS, 065:13:18, was as follows: PCAD MODE = NPNT CONTROL LAW FLAG = NPNT Stars: = 8 FIDS = 0 RA = 185.199 deg Dec = -29.002 deg ROLL = 30.168 deg Format = 2 OBSID = 60822 ACIS CTI SIM FA = -535 SIM TSC = -99616 (HRC-S) HETG = IN ( 6.34 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. Triggers) P41GM = 0.0 LT 8.47 A-leak = 1.0200 mu-a B-leak = 1.0200 mu-a Descending through 76594 km. ACIS focal plane temperature -119.9. NOTES/ISSUES/PROBLEMS From the 9am status meeting: 5 supports, one was a test by DSS-46. Test had some minor issues, which imply that we still need to transmit at 256kbps when further than 100,000 km. Last load segment of MAR0303D was uplinked, on-board loads are good until 068:07:52. (The reworked part of the load to correct the ACIS configuration is in SCS 129, which starts execution at 066:08:30.) MAR1003A loads were accepted. Will be signed off this morning. Good Work! EPHIN yellow limits have tripped as expected, due to the long simultaneous XMM observation at 101 deg pitch angle. 5EPHINT is highest of mission at 35.1 deg C. Some backstop changes to be presented to FD CCB today. ASVT work this afternoon.
