Shift L3346. Start at 262:12:00 GMT = 08:00am 18 Sep EDT End 10:00am 18 Sep SOT Lead DAS (Times will be given in GMT on day 262.) PLAN ---- Continue running load SEP1508B. Measure ACIS cti surrounding perigee passage. Upon egress to obsid 9735, an ACIS-I observation of the Extended Groth Strip to compare with multiwavelength data of the AEGIS project and study AGN evolution.

DISABLED) P41GM = 0.0 LT 8.47 Descending through 64989 km. ACIS focal plane temperature -119.7 degC. EPH temp: 104.89 degF NOTES/ISSUES/PROBLEMS From the 9am status meeting: Three supports over the past day. DSS-66 lost telemetry for 5 minutes, but reset with no impact. One stored command sequence was uplinked, on-board loads good until 266:08:05. SEP2208A products reviewed yesterday, SEP2208B products are out for email review by noon today. ACIS focal plane cooling test only reached about -123.2 deg C. Preliminary assessment is that this is warmer than expected due to tail sun orientation. MATLAB control board approved 2008-261 full release yesterday. Will be installed after SEP2208 load products are approved. A T1 line is down -- working with JPL and ATT to diagnose and restore. Limits current data rate capability but not overall function. A NetApp failover occurred yesterday and repeated this morning after a return. NetApp called in an working problem.
