Shift L2743. Start at 024:13:00 GMT = 08:00am 24 Jan EST End 11:00am 24 Jan SOT Lead DAS (Times will be given in GMT on day 024.) PLAN ---- Continue running load JAN2207A. Perform cti measurements surrounding perigee passage. Start the next orbit with obsid 7694, an ACIS-I GTO observation of PKS0745-191 to look for X-ray outbursts in rich clusters of galaxies.

EPH temp: 103.64 degF EPH 27V: 12.20 NOTES/ISSUES/PROBLEMS ACIS has been warmer than -119 for much of this orbit. From the 9am status meeting: Two supports over the past day, no issues. JAN2907A products out yesterday for a load review at 2pm today. The limit trip reported yesterday has been confirmed as a double bit error.
