Shift L1903. Start at 280:12:00 GMT = 08:00am 06 Oct EDT End 10:00am 06 Oct SOT Lead DAS (Times will be given in GMT on day 280.) PLAN ---- Continue running load OCT0404A. Finish obsid 4652, an ACIS-S observation of the supernova remnant G352.7-0.1, to discover the sites of nucleosynthesis producing super-solar elemental abundances. Then continue the Perseus cluster series with obsid 4946.

EPH temp 90.56 F NOTES/ISSUES/PROBLEMS ACIS is slightly warm during a science observation, but within 2 degree limit. From the 9am status meeting: Three supports over the past day. At this morning's support simulated data from DSS-16 was flowing simultaneously with the real dump data from DSS-24, which caused a spurious ACIS warm radiator warning. We believe we ultimately got a proper dump of TM data. One load segment was uplinked, on-board loads are good until 283:19:05. The OCT1104A products were approved in yesterday's load review. However they won't be signed or put into the data base while we await direction on a three-day ToO request which came in yesterday. The OCC web2 transition was successful yesterday. Star Selection and Aspect Working Group will meet at 10am today.
