Shift L1762. Start at 139:12:00 GMT = 08:00am 18 May EDT End 10:00am 18 May SOT Lead DAS (Times will be given in GMT on day 139.) PLAN ---- Continue running load May1704B. Do obsid 4793, an ACIS-S observation of F1525-7250, as part of a survey to determine the local luminosity function of a set of spectroscopically selected AGN. Then perform CTI measurements surrounding perigee passage. No Comm this shift.

Triggers) P41GM = 0.0 LT 8.47 A-leak = 1.0200 mu-a B-leak = 1.0200 mu-a Descending through 75253 km. ACIS focal plane temperature -119.9 C. EPH temp 98.62 F NOTES/ISSUES/PROBLEMS TEPHIN temperature is 5.5 degF over its maximum predicted for the week. Last evening's SOT shift reported it at 6.8 degF over maximum. (The prediction incorporates ~10 deg margin below the red limit.) There will be a debrief of the ACIS software patch load failure, at 10am this morning, May 18, on 405-244-5060, pass code 1165# From the 9am status meeting: Three supports over the past day. No issues. No uplinks, on-board loads good until 142:15:50. MAY2404A products expected out later today for a load review tomorrow. (No load review today.) ACIS software patch load failure has been diagnosed as an incorrect ground file used for comparison to the memory dump. The uploaded software was correct. Debrief at 10am this morning. Look Ahead: This Thursday, May 20, at 1pm in the action room, there will be a "roll-out" and demonstration of the new ifot (Integrated Flight Operations Tools). All are welcome, and there will be provision for following by telephone.
