Shift L2685. Start at 331:13:00 GMT = 08:00am 27 Nov EST End 10:00am 27 Nov SOT Lead DAS (Times will be given in GMT on day 331.) PLAN ---- Continue running load NOV2706A. Go through perigee passage and do ascending CTI measurements. Then obsid 8453, an ACIS-S/HETG observation of the active M dwarf binary EQ Peg to look for spectral signatures of variability in the plasma properties. Next Comms: 331:1920 to 2020 332:0330 to 0430 332:1215 to 1315 332:2000 to 2100 333:0345 to 0445 Orbital events: 2006:331:16:56:43.861 1009 EPERIGEE ORBIT PERIGE 2006:333:00:41:41.770 1010 EAPOGEE ORBIT APOGEE 2006:334:08:25:23.424 1010 EPERIGEE ORBIT PERIGEE 2006:335:16:09:12.999 1011 EAPOGEE ORBIT APOGEE 2006:336:23:53:38.192 1011 EPERIGEE ORBIT PERIGEE 2006:338:07:36:39.942 1012 EAPOGEE ORBIT APOGEE 2006:339:15:20:46.448 1012 EPERIGEE ORBIT PERIGEE EVENTS ------ Status at LOS, 331:12:38, was as follows: PCAD MODE = NPNT CONTROL LAW FLAG = NPNT Stars: = 5 FIDS = 3 RA = 90.001 deg Dec = 39.002 deg ROLL = 119.844 deg Format = 2 OBSID = 58668 perigee attitude SIM FA = -535 SIM TSC = -99616 (HRC-S) DITHER = ENAB HETG = OUT (79.09 deg) LETG = OUT (77.59 deg) HRC-I HV is ON EPHIN Geom = SMAL E150 = 1710829.3 E300 = 15554.0 E1300 = 40.3 LT 20.0 (RADMON P4GM = 1875.3 LT 300.

EPH temp: 101.13 degF EPH 27V: 13.30 NOTES/ISSUES/PROBLEMS Review of CAP 1016 at 9:30 EDT approved cooling of the ACA by 1 degree C, to -16 C, en route to cooling to -20 degree C. Preliminary results of the pre-cooling calibration showed performance as expected from extrapolation from the previous calibration. From the 9am status meeting: 9 supports over the weekend. No issues over the past 4 day holiday. Dark current calibration was run Friday night, appears nominal. Two stored command segments were uplinked, on-board loads are good until 336:20:35. Products for DEC0406A are expected out this morning. ACE solar protons near background level. Sun is very quiet. (Shhh!) There will be a telecon on 405 244 5060 1165# at 11:30am EDT this morning to discuss the test results on the tertiary data base update.
