Shift L1120. Start at 227:12:00 GMT = 08:00am 15 Aug EDT End 12:00 noon 15 Aug SOT Lead DAS (Times will be given in GMT on day 227.) PLAN ---- Continue running load AUG1302B. Do CTI upon perigee egress, then ACIS-S/HETG obsid 2534 of the long period RS CVn binary system IM PEG. Next Comms: 227:1700 to 1800 228:0300 to 0400 228:1100 to 1200 228:2000 to 2100 229:0500 to 0600 229:1430 to 1530 229:2300 to 0000 230:0930 to 1030 230:2015 to 2115 Orbital events: 2002:228:15:00:43.852 418 ORBIT APOGEE 2002:229:22:45:12.442 418 ORBIT PERIGEE 2002:231:06:28:13.647 419 ORBIT APOGEE 2002:232:14:13:13.137 419 ORBIT PERIGEE 2002:233:21:56:14.118 420 ORBIT APOGEE 2002:235:05:40:28.257 420 ORBIT PERIGEE 2002:236:13:24:03.689 421 ORBIT APOGEE 2002:237:21:07:44.392 421 ORBIT PERIGEE EVENTS ------ Status at LOS, 227:09:04, was as follows: PCAD MODE = NPNT CONTROL LAW FLAG = NPNT Stars: = 7 FIDS = 0 RA = 344.503 deg Dec = 15.000 deg ROLL = 145.092 deg Format = 2 OBSID = 61083 ACIS CTI SIM FA = -467 SIM TSC = -99616 (HRC-S) HETG = IN ( 5.96 deg) LETG = OUT (77.96 deg) HRC-S HV is ON EPHIN Geom = LARG E1300 = 2699.2 (RADMON IS P4GM = 10601.6 DISABLED) P41GM = 6.8 A-leak = 1.0200 mu-a B-leak = 0.3200 mu-a Ascending through 33906 km. ACIS focal plane temperature -116.3 NOTES/ISSUES/PROBLEMS HETG angle readout shifted one bit from 6.34deg to 5.96 deg around 227:08:27. ACE rates are somewhat elevated, 112-187 keV flux~10,000, but we are at perigee now, and then will use the HETG for 8 hours, and only have about 2 subsequent hours of ACIS exposure before moving to the HRC/LETG. From the 9am status meeting: Three supports, no spacecraft problems. CDR having problems getting data to the OCC, but no loss expected. The last segment of the AUG1302B loads was uplinked, so on-board loads are good until 231:07:12 AUG1902B products are out for a 1pm load review today. FD CCB today will hear a briefing on the Sept 7 Lunar eclipse plans. Quick look data: OBSID Target Time Comment ----- ------ -------------- ------- 4357 GROTH-WESTPHAL 224:23:03: ACIS-I NONE 88 Ksec, interrupted by GRB TOO, looks good 4364 GRB020813 225:23:46 ACIS-S HETG 26 Ksec partial, 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 -------------------------------------------------------
