Performing CTI measurements during perigee passage. No comm this shift. Next Comms: 015:1825 to 1925 015:2340 to 0140 016:0730 to 0830 016:2245 to 0045 017:0505 to 0605 017:1505 to 1605 Orbital events: 2002:015:17:55:53.840 EPERIGEE 337 ORBIT PERIGEE 2002:017:01:39:12.934 EAPOGEE 338 ORBIT APOGEE 2002:018:09:23:31.345 EPERIGEE 338 ORBIT PERIGEE 2002:019:17:07:25.230 EAPOGEE 339 ORBIT APOGEE EVENTS ------ Status at LOS, 015:10:28, was as follows: PCAD MODE = NPNT CONTROL LAW FLAG = NPNT Stars: = 8 FIDS = 0 RA = 178.002 deg Dec = -6.000 deg ROLL = 63.560 deg Format = 2 OBSID = 61349 CTI measurement SIM FA = -467 SIM TSC = -99616 (HRC-S) HETG = OUT (79.46 deg) LETG = OUT (77.96 deg) HRC-I HV is ON EPHIN Geom = LARG E1300 = 0.9 LT 10.0 (RADMON P4GM = 14.7 LT 300. Triggers) P41GM = 0.1 LT 8.47 A-leak = 0.4840 mu-a B-leak = 0.0880 mu-a Descending through 72601 km. ACIS focal plane temperature -118.9. NOTES/ISSUES/PROBLEMS Note that ACIS focal plane is warming on inbound leg. From the 9am status meeting: An email review of JAN2102A yesterday revealed that the schedule did not sufficiently overlap for a coordinated HRC-S LETG observation with HST, for V471 Tau. Schedule will be reworked today, next load review is probably tomorrow. Mission planning is moving all products to the 3rd string to avoid conflict or delay due to the installation of ONLS 3.8 which will take place tomorrow. The 3.8 upgrade will commence at LOS 016:0840 tomorrow at should be complete before next contact setup at 2145. There will be a tagup at 3pm EST tomorrow for a GO/NOGO/BACKOUT decision. We have already verified that the 3rd string is operational so there is no problem in case the upgrade is not operational for the 2245 comm support. ASVT testing 2 to 6pm EST today to do OBC hardware dead dumps. This was a problem in the last simulation. Quick look data: OBSID Target Time Comment ----- ------ -------------- ------- 1966 PSR B0833-45 013:20:45 HRC-I NONE Looks good. 2733 GX 301-2 013:09:15 ACIS-S HETG Looks good. 3153 PSS0209+0517 014:11:17 ACIS-S NONE Target not visible ------------------------------------------------------- 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 -------------------------------------------------------
