NOTES/ISSUES/PROBLEMS ACIS focal plane was warm, -118.1, towards the end of obsid 60979 cti measurement. At the start of the science run on NGC 2264 it was only down to -118.3. From the 9am status meeting: Twelve supports over the weekend. Some minor glitches with DSN ground station equipment had no impacts. Three load segments of OCT2802B were uplinked, on-board loads good until 305:06:50. NOV0402 products are due out this morning, for a phone-in load review at 2pm this afternoon. Dan Shropshire visited TRW west last week, gave a briefing on the software tools FOT has developed inhouse. He reported that Peter Quast is returning to TRW, and can be a potential resource to us. A training session by Rich Logan on mechanism load review will be scheduled later this week. There will be a telecon at 2:30 pm EST today, on (405) 244-5060 1165# to brief Marc Osborne on the results of our CRM telecons.
