Shift L1365. Start at 107:13:00 GMT = 08:00am 17 Apr EDT End 10:00am 17 Apr SOT Lead DAS (Times will be given in GMT on day 107.) PLAN ---- Continue running load APR1403A. Finish obsid 3577, an ACIS-S observation of the cluster of galaxies RCS0439.6-2905, as part of a survey to study the Lx-T relation and the morphology of clusters at redshifts 0.8 < z < 1.1. That will take the rest of the orbit into perigee passage.

Status essentially unchanged. NOTES/ISSUES/PROBLEMS Voice loop box at SOT lead station not functional. Reported to GOT. From the 9am status meeting: Three supports over the past day. DSS-16 had a hydralic failure and couldn't support, so used DSS-24 to complete dump, then switched to DSS 27 for firewall testing. One SCS uplinked, on-board loads good until end of current week, 110:13:50. APR2103A loads were signed-off yesterday. APR2803A now in work. FOT/MP will schedule regular load review times only on Tuesday and Wednesday, at 2pm, because the load creation cycle has been shorter on average since the new SAUSAGE has been used. Necessary reviews on other days will be scheduled as special cases as needed. FOT will continue ASVT testing today of various branches in the IRU swap proceedure.
