Shift L2381. Start at 027:13:00 GMT = 08:00am 27 Jan EST End 11:00am 27 Jan SOT Lead DAS (Times will be given in GMT on day 027.) PLAN ---- Continue running load JAN2306B. Go through perigee passage and do ascending ACIS CTI measurement. Then do obsid's 6794 and 6795, an ACIS-I search for AGN in the cluster of galaxies Abell 754.

Status is essentially unchanged. NOTES/ISSUES/PROBLEMS From the 9am status meeting: Three supports over the past 24 hours. The COG was down for 13 minutes, but was recycled and all telemetry acquired. JAN3006B products were approved yesterday. FEB0606 products are expected out late today for a load review on Monday. New power supplies for the ASVT tie card rack have arrived. Expected to be running by Monday. Solar protons continue at background level, and solar activity expected to be very low.
