Shift L937. Start at 044:13:00 GMT = 08:00am 13 Feb EST End 10:00am 13 Feb SOT Lead DAS (Times will be given in GMT on day 044.) PLAN ---- Continue running load FEB1102D. Performing ACIS CTI measurement, then will go through perigee. The entire next orbit is the ACIS-I obsid 3294, HDF-N deep survey.

Triggers) P41GM = 0.0 LT 8.47 A-leak = 1.0200 mu-a B-leak = 0.4440 mu-a Descending through 81683 km. ACIS focal plane temperature -118.3. NOTES/ISSUES/PROBLEMS High ACIS focal plane temperature probably invalidates CTI measurement 61310. From the 9am status meeting: Three nominal supports. One load segment uplinked, on-board command loads good until 047:13:03. FEB1802B load was approved yesterday. No load review today. Work will start on FEB2502 planning. That load will have the anomalously short rad belt entry to perigee time -- this time will be made a minimum of 6 hours in the absence of any other advice or information. Roger will lead a tour of science writers, here for the AAAS meeting in Boston, through the OCC this afternoon. No SSAWG meeting today. There will be an ASVT models telecon today at 2pm EST on 405-244-5060 pin 1165# Quick look data: OBSID Target Time Comment ----- ------ -------------- ------- 2545 M 1-16 042:14:39 ACIS-S Looks good 2718 GRS 1758-258 043:05:49 HRC-I Looks good 3084 M87 043:09:21 ACIS-S Looks good ------------------------------------------------------- Dan Schwartz, MS #3 das@head-cfa.harvard.edu phone: (617)495-7232 FAX: (617)495-7356 cell phone: (617)512-5627 pager: 877-693-7198 PIN 693-7198 or e-mail 6937198@archwireless.net -------------------------------------------------------
