Shift L1173. Start at 280:12:00 GMT = 08:00am 07 Oct EDT End 12:00 noon 07 Oct SOT Lead DAS (Times will be given in GMT on day 280.) PLAN ---- Continue running load OCT0502B. (This load was created for the TOO for GRB 021004, and replaces OCT0702C. The sequence formerly in OCT0702C is unchanged in OCT0502B). Exit from perigee and do OBSID 3233, an ACIS-I observation of the galaxy cluster Abell 115 containing the radio galaxy 3C 28.0. This is followed by OBSIDs 3247, and 3284, ACIS-I observations of the clusters of galaxies A2409 and MACS J2211.7-0349. Next Comms: 280:1500 to 1600 280:1940 to 2140 281:0600 to 0700 281:1550 to 1750 282:0100 to 0200 282:1100 to 1200 282:1950 to 2150 283:0640 to 0840 283:1615 to 1715 Orbital events: 2002:280:04:32:07.880 437 EPERIGEE ORBIT PERIGEE 2002:281:12:15:51.600 438 EAPOGEE ORBIT APOGEE 2002:282:19:58:59.135 438 EPERIGEE ORBIT PERIGEE 2002:284:03:42:27.940 439 EAPOGEE ORBIT APOGEE 2002:285:11:26:45.899 439 EPERIGEE ORBIT PERIGEE 2002:286:19:09:57.448 440 EAPOGEE ORBIT APOGEE EVENTS ------ Status at LOS, 280:06:58, was as follows: PCAD MODE = NPNT CONTROL LAW FLAG = NPNT Stars: = 8 FIDS = 0 RA = 0.002 deg Dec = 0.001 deg ROLL = 293.419 deg Format = 2 OBSID = 61006 ACIS CTI SIM FA = -990 SIM TSC = -99616 (HRC-S) HETG = OUT (79.46 deg) LETG = IN ( 4.46 deg) HRC-S HV is ON EPHIN Geom = SMALL E1300 = 263.2 LT 10.0 (RADMON P4GM = 22547.4 LT 300.

ACIS focal plane temperature -118.4. 15:57 LOS Status is essentially unchanged. Ascending through 91296 km. ACIS focal plane temperature -118.3. NOTES/ISSUES/PROBLEMS ACIS temperature is quite high. Our recommended "spec" for V&V allows two degrees of warming, to -118.0, so V&V should take a close look at this. From the 9am status meeting: Ten supports over the weekend, no problems. One support was a 26m upgrade test, and one was an extra 34m contact to uplink the TOO load. The TOO load uplinked the first two segments of OCT0502B, which replaced the end of SEP3002B and the start of OCT0702C. On board loads are good until 284:02:03. OCT1402 products are out this morning for an email review today. The Gamma Ray Burst 24-hr response TOO was very successful. Thanks to all for accomplishing this. Solar proton fluxes are very low, almost at background levels.
