Shift L1821. Start at 198:12:00 GMT = 08:00am 16 Jul EDT End 10:00am 16 Jul SOT Lead DAS (Times will be given in GMT on day 198.) PLAN ---- Continue running load JUL1204B. Doing obsid 4657, an ACIS-S observation of the pulsar wind nebula at PSR 0355+54 to study morphology, and search for a torus and jet. Next Comms: 198:1300 to 1400 198:2245 to 2345 199:0345 to 0445 199:1150 to 1340 199:2015 to 2115 200:0330 to 0430 200:0730 to 1100 penumbral eclipse coverage 200:0730 to 1100 penumbral eclipse coverage 200:1045 to 1200 penumbral eclipse coverage 200:1900 to 2000 201:0345 to 0445 201:1100 to 1200 Orbital events: 2004:198:01:02:07.648 682 EPERIGEE ORBIT PERIGEE 2004:199:08:45:20.652 683 EAPOGEE ORBIT APOGEE 2004:200:16:29:56.065 683 EPERIGEE ORBIT PERIGEE 2004:202:00:13:15.508 684 EAPOGEE ORBIT APOGEE 2004:203:07:57:14.225 684 EPERIGEE ORBIT PERIGEE 2004:204:15:40:48.964 685 EAPOGEE ORBIT APOGEE 2004:205:23:24:22.575 685 EPERIGEE ORBIT PERIGEE EVENTS ------ Status at AOS, 198:13:01, was as follows: PCAD MODE = NPNT CONTROL LAW FLAG = NPNT Stars: = 5 FIDS = 3 RA = 59.745 deg Dec = 54.202 deg ROLL = 74.995 deg Format = 2 OBSID = 4657 PSR 0355+54 SIM FA = -467 SIM TSC = 75623 (ACIS-S) DITHER = ENAB HETG = OUT (79.46 deg) LETG = OUT (77.59 deg) HRC-I HV is ON EPHIN Geom = LARG E150 = 0.7 E300 = 0.0 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 = 0.2880 mu-a Ascending through 89279 km. ACIS focal plane temperature -119.5 degC. EPH temp 68.89 degF 13:58 LOS. Status is essentially unchanged. Ascending through 92980 km. ACIS focal plane temperature -119.7 degC. EPH temp 69.70 degF. NOTES/ISSUES/PROBLEMS Due to CfA computer facility problems, HEAD network couldn't be logged into at start of shift. Problem was cleared just after start of comm. From the 9am status meeting: Three supports over the past day. DSS-46 had to lower telemetry rate to 256K, this lengthened the ACIS CAP 923. CAP 923 was successfully run to dump BEP memory, warm reboot, and repeat memory dump: see report Jul_15_2004_H1820_acis.txt. On-board loads are good until 200:08:11:59, the start of the penumbral eclipse. Load review for JUL1904B planned for 10:30am. Due to earlier problems with DSS-24, the SSR filled side A and rolled over to side B. Data has been cleared from side B and we expect to switch back to SSR-A today. Database backups were completed last night. GOT is putting telemetry into time order to transmit to CXC/dataops. NGST FOT/west coast telecon at 11am to discuss recompilation of the on-board software. Quick look data: No new quick looks due to CF problems. ------------------------------------------------------- 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 -------------------------------------------------------
