Shift L1303. Start at 045:13:00 GMT = 08:00am 14 Feb EST End 12:00 noon 14 Feb SOT Lead DAS (Times will be given in GMT on day 045.) PLAN ---- Continue running load FEB1003B. Two long ACIS-I observations, obsids 3926 and 4415, of the nearby elliptical galaxy NGC4636 to study the feedback between cooling flows and AGN in detail. Then finish the orbit with ACIS-S obsid 4012, of the IR-bright LINER NGC 3125 -- part of a snapshot survey. Next Comms: 045:1205 to 1405 045:2010 to 2210 046:0600 to 0800 046:1050 to 1250 046:2305 to 0055 047:0850 to 1050 047:2030 to 2130 048:0440 to 0640 048:1230 to 1330 048:2010 to 2210 Orbital events: 2003:046:02:08:11.501 487 EAPOGEE ORBIT APOGEE 2003:047:09:53:14.789 487 EPERIGEE ORBIT PERIGEE 2003:048:17:36:05.373 488 EAPOGEE ORBIT APOGEE 2003:050:01:20:08.629 488 EPERIGEE ORBIT PERIGEE 2003:051:09:03:24.847 489 EAPOGEE ORBIT APOGEE 2003:052:16:46:40.688 489 EPERIGEE ORBIT PERIGEE 2003:054:00:30:08.583 490 EAPOGEE ORBIT APOGEE 2003:055:08:14:02.080 490 EPERIGEE ORBIT PERIGEE EVENTS ------ Status at LOS, 045:14:04, was as follows: PCAD MODE = NPNT CONTROL LAW FLAG = NPNT Stars: = 5 FIDS = 3 RA = 190.729 deg Dec = 2.697 deg ROLL = 73.625 deg Format = 2 OBSID = 3926 NGC 4636 SIM FA = -535 SIM TSC = 89823 (ACIS-I) 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 ACIS temperature warmed from -119.7 to -119.5 during the comm. From the 9am status meeting: Three supports over the last day, no problems. On-board loads good until 048:07:54. FEB2403 week, with the Jupiter pointings, is just starting planning. EPHIN temperature tripped yellow limit at 95 deg F. A lost VCDU during obsid 3902 corrupts the bias file. A reconstruction for quick look seems ok. Database 1 down this morning for reboot. Quick look data: OBSID Target Time Comment ----- ------ -------------- ------- 3902 PSR J2021+3651 043:12:02 ACIS-S NONE CC mode, missing VCDU corrupts bias 3812 CYG X-3 043:17:44 HRC-I NONE Looks good. Check HRI streaking 4010 NGC 660 043:22:25 ACIS-S NONE Target not obvious 2942 NGC1404 044:00:16 ACIS-S NONE Looks good ------------------------------------------------------- Dan Schwartz, MS #3 das@head-cfa.harvard.edu phone: (617)495-7232 FAX: (617)495-7356 cell phone: (617)512-5627 pager: 877-693-7198 PIN 693-7198 or e-mail 6937198@archwireless.net -------------------------------------------------------
