Shift L1530. Start at 272:12:00 GMT = 08:00am 29 Sep EDT End 10:00am 29 Sep SOT Lead DAS (Times will be given in GMT on day 272.) PLAN ---- Continue running load SEP2903A. Do obsid 4445, an ACIS-S observation of the black hole candidate GX 339-4 (first identified optically by the HEAO-1 scanning modulation collimator position), to search for an X-ray counterpart to the radio jet which was ejected in May 2002. Next Comms: 272:2030 to 2130 273:0250 to 0450 273:1315 to 1515 273:2030 to 2130 274:0515 to 0615 274:1220 to 1420 274:2200 to 2300 275:0345 to 0445 275:1245 to 1345 275:2030 to 2130 Orbital events: 2003:272:04:12:16.396 572 ORBIT PERIGEE 2003:273:11:55:41.043 573 ORBIT APOGEE 2003:274:19:39:38.874 573 ORBIT PERIGEE 2003:276:03:22:47.390 574 ORBIT PERIGEE 2003:278:18:50:25.624 575 ORBIT APOGEE 2003:280:02:33:43.018 575 ORBIT PERIGEE 2003:281:10:18:01.199 576 ORBIT APOGEE 2003:282:18:01:15.987 576 ORBIT PERIGEE 2003:284:01:45:50.301 577 ORBIT APOGEE EVENTS ------ Status at AOS, 272:11:53, was as follows: PCAD MODE = NPNT CONTROL LAW FLAG = NPNT Stars: = 5 FIDS = 3 RA = 255.690 deg Dec = -48.775 deg ROLL = 256.473 deg Format = 2 OBSID = 4445 GX339-4 SIM FA = -467 SIM TSC = 75623 (ACIS-S) DITHER = ENAB HETG = OUT (79.46 deg) LETG = OUT (77.59 deg) HRC-S HV is ON EPHIN Geom = LARG E150 = 12.3 E300 = 0.4 E1300 = 0.0 LT 10.0 (RADMON P4GM = 0.3 LT 300. Triggers) P41GM = 0.0 LT 8.47 A-leak = 1.0200 mu-a B-leak = 0.7080 mu-a Ascending through 70114 km. 12:45 LOS. Status is essentially unchanged. Ascending through 74617 km. ACIS focal plane temperature -119.4. NOTES/ISSUES/PROBLEMS From the 9am status meeting: 9 supports over the weekend. Some issues, e.g. with the ground stations locking up, but no impacts on data receipt. Three load segments were uplinked, so on-board loads are good until 276:10:16. OCT0603A products have been out for review. Today's review is email ONLY. This is because the last observation in SEP2903A is being rescheduled, so the OCT0603 week will be rescheduled to start earlier to replace obsid 3822 of HER X-1, previously scheduled for 278:21:19. Thermal status meeting is planned for 11am EDT this Thursday, Oct 2. Draper plans a power outage next weekend, from 7am EDT Saturday Oct 4 through as long as midnight Sunday Oct 5. Details to be determined during this week.
