Shift L2209. Start at 220:13:00 GMT = 08:00am 08 Aug EDT End 10:00am 08 Aug SOT Lead DAS (Times will be given in GMT on day 220.) PLAN ---- Continue running load AUG0805C. Perform ACIS CTI measurements surrounding perigee passage. Upon egress do obsid 5403, an ACIS-I observation of young stellar objects in the Coronet Cluster to monitor for X-ray and Radio flares.

EPH temp 87.33 degF Status at LOS, 220:13:09, is essentially unchanged. Descending through 52472 km. ACIS focal plane temperature -119.9 degC. EPH temp 87.33 degF NOTES/ISSUES/PROBLEMS From the 9am status meeting: Nine supports over the weekend. DSS-54 had an unknown antenna problem causing tracking problems. We switched to DSS-66 and got a partial dump. DSS-54 finished fix during next pass. Three load segments of AUG0805C were uplinked. On-board loads good until 224:08:11. AUG1505 products in work. Expected to be released soon for a 2pm load review today. The observation of SS433 was very successful, and observers are going ahead with followups in this week's and next week's load. This avoids a "reverse" ToO to remove the followup from this week's load. A 3-week DDT ToO to followup GRB 050709 is pending. ACIS DEA high voltage toggled the yellow alarms on day 217, as expected during the focal plane heating test. TLM2 server was lost this weekend. Being worked on. Affects ASVT use only. IVODS is down 8am to 2pm today for software patches.
