Do obsid 7073, an ACIS-S observation of NGC 3379 as part of a program to study the Low Mass X-ray Binary population in nearby elliptical galaxies. Next Comms: 023:2145 to 2245 024:0345 to 0445 024:1315 to 1415 024:2045 to 2145 025:0345 to 0445 025:1445 to 1545 025:2200 to 2300 Orbital events: 023:15:38:45.989 893 EAPOGEE ORBIT APOGEE 024:23:22:24.802 893 EPERIGEE ORBIT PERIGEE 026:07:06:02.912 894 EAPOGEE ORBIT APOGEE 027:14:49:21.200 894 EPERIGEE ORBIT PERIGEE 028:22:33:45.978 895 EAPOGEE ORBIT APOGEE 030:06:16:38.371 895 EPERIGEE ORBIT PERIGEE 031:14:01:43.075 896 EAPOGEE ORBIT APOGEE EVENTS ------ Status at LOS, 023:13:38, was as follows: PCAD MODE = NPNT CONTROL LAW FLAG = NPNT Stars: = 5 FIDS = 3 RA = 161.974 deg Dec = 12.576 deg ROLL = 73.980 deg Format = 2 OBSID = 7073 NGC3379 SIM FA = -467 SIM TSC = 75624 (ACIS-S) DITHER = ENAB HETG = OUT (79.09 deg) LETG = OUT (77.59 deg) HRC-I HV is ON EPHIN Geom = SMAL E150 = 24.4 E300 = 2.0 E1300 = 3.9 LT 20.0 (RADMON P4GM = 0.0 LT 300. Triggers) P41GM = 0.0 LT 8.47 A-leak = 1.0200 mu-a B-leak = 1.0200 mu-a Ascending through 126383 km. ACIS focal plane temperature -119.5 degC. EPH temp 97.37 degF NOTES/ISSUES/PROBLEMS From the 9am status meeting: Nine supports over the weekend. A problem with communications at JPL led to a 12 minute dropout of voice and telemetry. Problem was fixed and there was no impact on objectives. Three stored command segments were uplinked, on-board loads are good until 027:10:45. Products for JAN3006 may be out tomorrow. EPHIN rail voltage was tripped, as expected by the predicted high temperature. ACE Solar proton rates are at background level. Solar activity expected to be extremely low over the next three days. ACIS is looking to run an engineering request to dump the on-board tables of bad pixels. FOT is building a command sequence to accomplish this.
