PLAN ---- Continue running load JUN1107A, with obsid 8557, an ACIS-I observation of the cluster Abell 2744, undergoing a violent merger at redshift z=0.31. Then start the interrupt load JUN1407A with obsid 8562, the fast DDT/ToO ACIS-S/HETG observation of the new source Swift J195509.6+2614, to investigate its classification.

EPH temp: 96.12degF EPH 27V: 18.30 NOTES/ISSUES/PROBLEMS We are observing a target, with ACIS-I at least 1.5 degree warmer than the set point. Since this is a cluster of galaxies, there may be issues fitting the spectrum. From the 9am status meeting: Three supports over the past day. DSS-46 LOS (line-of-sight) file was not accurate so uplink was not ossible until 21:41. Support was extended 30 minutes to complete all requirements. Three segments of the JUN1407A interupt load were uplinked. On-board loads are good until 169:01:35. The JUN1407A ToO products were approved yesterday, and uplinked. JUN1807B products should be circulated this morning. From the IST weekly tagup: Next issue of the TDB should be built the first week in July, hopefully containing a to-be-approved change of the EPHIN temperature red limit. Within a few weeks the FOT/MP will be developing a schedule for testing of the CRM updates to the OFLS, and coordinating the necessary SOT testing. We need to define and implement appropriate security for the OCC Twiki, particularly to ensure ITAR compliance. Peter Quast will be visiting all next week to work on recompile PCAD issues, and implementing long maneuvers in ASVT.
