Shift L2021. Start at 032:13:00 GMT = 08:00am 01 Feb EST End 10:00am 01 Feb SOT Lead DAS (Times will be given in GMT on day 032.) PLAN ---- Continue running load JAN3105B. Finish obsid 6186, an ACIS-I observation to study interaction between energy outbursts from the supermassive black hole (SMBH) in M87 and its surrounding gaseous atmosphere. Then do CTI measurements surrounding perigee passage.

EPH temp 99.88 deg F NOTES/ISSUES/PROBLEMS ACIS is running warm. From the 9am status meeting: Three supports in past 24 hours. DSS-24 had no telemetry at start. Significant amounts of data were missing, so we redumped at DSS-66 contact, but only got a small amount so we are still trying to catch up on the SSR dump data. One weekly load segment was uplinked; on-board loads are good until 035:21:03. Products for FEB0705A are expected out today for a load review tomorrow. ACIS will likely repeat the focal plane cooling tests during a long HRC observation in the week of FEB1405, but they are still awaiting information on whether the earth was in the radiator field of view during the day 022 test.
