EPH temp 50.69 degF NOTES/ISSUES/PROBLEMS ACIS is running 0.7 to 0.8 degrees warm during the current observation of CL 0230+1836. Note high E150 and E300 rates, presumably due to the CME's earlier this week. Soft protons are elevated to a few 100's, but already are hinting at turning over. However, there were two more CME's yesterday. From the 9am status meeting: Two supports over the past day. Needed to redump the data from yesterday's DSS-24 (Goldstone) pass, where we apparently had two data streams. Actually, Joy reported this as "one and a half" data streams. The additional problem besides the two streams was that the data quality was reported as 100%, which was not correct, as processing found many nonsensical limit trips. Last night's DSS-24 pass had problems -- after they switched their data controller we retrieved a partial dump, and avoided spilling over to SSR B. NOV0804B incorporated some minor changes, and is in email review, with approval expected today. Yesterday's flight director's CCB accepted the HRC -Y Shutter Anomaly Failure Report, and Rino's lunar eclipse briefing. Meeting today, 11am in action room and on 405-244-5060 1165#, for briefing the propellant line cooling situation.
