Shift L1064. Start at 171:12:00 GMT = 08:00am 20 Jun EDT End 12:00 noon 20 Jun SOT Lead DAS (Times will be given in GMT on day 171.) PLAN ---- Continue running load JUN1702C. Currently we are safed for perigee passage. Upon egress tonight, we do ACIS-I obsid 2544 of the late B-type star HD169978, and then resume the series of E0102-72.3 calibration observations. Next Comms: 171:2045 to 2145 172:0200 to 0300 172:0910 to 1010 172:1840 to 2040 173:0520 to 0620 173:1215 to 1315 173:1900 to 2000 174:0230 to 0330 174:1240 to 1440 174:2205 to 2305 Orbital events: 2002:171:18:25:03.429 396 ORBIT PERIGEE 2002:173:02:08:54.088 397 ORBIT APOGEE 2002:174:09:53:00.071 397 ORBIT PERIGEE 2002:175:17:36:24.353 398 ORBIT APOGEE 2002:177:01:21:33.978 398 ORBIT PERIGEE 2002:178:09:04:39.928 399 ORBIT APOGEE 2002:179:16:49:28.197 399 ORBIT PERIGEE 2002:181:00:32:59.733 400 ORBIT APOGEE EVENTS ------ Status at LOS, 171:12:19, was as follows: PCAD MODE = NPNT CONTROL LAW FLAG = NPNT Stars: = 8 FIDS = 0 RA = 147.001 deg Dec = -23.001 deg ROLL = 234.588 deg Format = 2 OBSID = 61157 ACIS CTI SIM FA = -535 SIM TSC = -99616 (HRC-S) HETG = OUT (79.46 deg) LETG = OUT (77.96 deg) HRC-I HV is ON EPHIN Geom = SMAL E1300 = 0.0 LT 10.0 (RADMON P4GM = 6.2 LT 300. DISABLED) P41GM = 0.0 LT 8.47 A-leak = 1.0200 mu-a B-leak = 0.0880 mu-a Descending through 62918 km. ACIS focal plane temperature -119.9. NOTES/ISSUES/PROBLEMS From the 9am status meeting: Three 34m supports in last 24 hours. Durring the DSS-34 pass the comm link to Canberra was lost for 11 min, then they had a transmitter problem for 14 min. The playback was restarted but not completed; however, it was caught up on the next pass. The week's last SCS load segment was uplinked, so on-board loads are good until 175:01:59. JUN2402C loads are out this morning. Only need aca/CM review, which should be done by email today. The problem with generating products under OFLS 9.3 was found to be a setup issue regarding a missing parameter in a namelist. FOT/MP will go back to 9.3 after the JUN2402 loads are approved. ASVT testing of the gyro K-constant updates did not take place yesterday due to ASVT problems.
