Shift L3087. Start at 003:13:00 GMT = 08:00am 03 Jan EST End 10:00am 03 Jan SOT Lead DAS (Times will be given in GMT on day 003.) PLAN ---- Continue running load DEC2407B. Do ACIS cti measurements on the on-board calibration source, surrounding perigee passage. Then do obsid 9095, an ACIS-S observation of the core-collapse supernova SN 2005kd, to characterize X-ray emission of this subclass at an age of a few years. Then resume ACIS-S observations of comet 8P_TUTTLE.

EPH temp: degF 103.64 EPH 27V: 26.84 NOTES/ISSUES/PROBLEMS From the 9am status meeting: Three supports over the past day, no issues. Last segment of the DEC2407B loads was uplinked, on-board loads good until 006:22:10. Working on JAN0708 products. Hope to have out late today, with a review early tomorrow (so that corrected products can be produced if necessary.) Last eclipse of the season will be during the afternoon pass. Then will run the preapproved CAP to disable SCS-29. Diagnosis of the CTU counter resets is in progress. Leading candidate so far is an SEU to the Master Telemetry Processor resulted in a Power On Clear signal. Commands have been executed normally since, and no operational response is anticipated to be needed. We have successfully recovered from yesterday's NAS failure, by completing the switchover to the NetApp system. All testing has been successful. Completion of the recovery of real time data is anticipated later this morning. Great efforts by the team resulted in no contacts being missed, no data lost!
