Shift L1474. Start at 216:12:00 GMT = 08:00am 04 Aug EDT End 10:30am 04 Aug SOT Lead DAS (Times will be given in GMT on day 216.) PLAN ---- Continue running load AUG0203A, which picked up from the SCS107 run and includes the week of Aug 4-10. Currently descending to perigee. Will run obsid 3918, an ACIS-S TOO observation of the "optically dark" gamma ray burst H2777. Next Comms: 216/2030-2130 DSS-24 217/0300-0400 DSS-24 217/1240-1440 DSS-66 Orbital events: 2003:216:15:32:55.772 551 EPERIGEE ORBIT PERIGEE 2003:217:23:16:20.962 552 EAPOGEE ORBIT APOGEE 2003:219:07:00:24.447 552 EPERIGEE ORBIT PERIGEE 2003:220:14:43:19.715 553 EAPOGEE ORBIT APOGEE 2003:221:22:28:01.964 553 EPERIGEE ORBIT PERIGEE 2003:223:06:11:00.825 554 EAPOGEE ORBIT APOGEE 2003:224:13:55:00.151 554 EPERIGEE ORBIT PERIGEE 2003:225:21:38:44.510 555 EAPOGEE ORBIT APOGEE 2003:227:05:22:14.136 555 EPERIGEE ORBIT PERIGEE 2003:228:13:06:27.914 556 EAPOGEE ORBIT APOGEE 2003:229:20:50:20.949 556 EPERIGEE ORBIT PERIGEE EVENTS ------ Status at LOS, 216:11:52, was as follows: PCAD MODE = NPNT CONTROL LAW FLAG = NPNT Stars: = 6 FIDS = 0 RA = 220.586 deg Dec = -10.869 deg ROLL = 252.354 deg Format = 2 OBSID = 60601 ACIS CTI SIM FA = -467 SIM TSC = -99616 (HRC-S) DITHER = ENAB HETG = OUT (79.46 deg) LETG = OUT (77.59 deg) HRC-S HV is ON EPHIN Geom = BAD E150 = 4928.0 E300 = 73.0 E1300 = 0.0 LT 10.0 (RADMON P4GM = 60.0 LT 300.

NOTES/ISSUES/PROBLEMS Cannot access the DSN schedule web page. How can the SOT get the DSN schedules? Darell will work on getting the text file posted on the OCCWEB page. From the 9am status meeting: Ten supports over the weekend. The current DSS 46 support didn't complete " . . . requirements due to equipment problems caused by transfer to new routing switch". DSS 46 continued debug operations after the end of the pass, and data seemed to flow at least intermittently. We will overflow SSR 1 at ~1700. Five load segments were uplinked, onboard loads good until 219:14:44 Got a battery disconnect glitch during Friday's eclipse. This was a single glitch, last observed about 18 months ago. Will run a CAP to clear it. FOT will run a safemode recovery exercise on ASVT tomorrow. SOT lead furniture for TST room reorganization should be available Friday.
