Shift L1302. Start at 044:13:00 GMT = 08:00am 13 Feb EST End 12:00 noon 13 Feb SOT Lead DAS (Times will be given in GMT on day 044.) PLAN ---- Continue running load FEB1003B. Go through perigee and measure ACIS CTI on egress. Then short ACIS-S observations, obsid 3999 of the radio-selected low-luminosity AGN NGC 4772, and obsid 4018 of the IR-bright LINER NGC 4666.

NOTES/ISSUES/PROBLEMS From the 9am status meeting: Three supports over the last day, no problems. Last segment of FEB1003B was uplinked. On-board loads good until 048:07:54. TEPHIN and 5EPHIN temperatures exceeded yellow limits, were up to 93.7 deg F, following observations of about 37ksec at 81 and 119 deg solar angles. Thermal Working Group will be today at 11:00am EST, in action room. Telecon: 405-244-5060 #1165.
