Finish obsid 5759, an ACIS-I observation of the cluster of galaxies cl0956+4107 as part of a high-z sample of ROSAT clusters. Then obsid 5927, an HRC-I observation of the supermassive black hole in M31. No comm this shift.

EPH temp 82.24 deg F NOTES/ISSUES/PROBLEMS From the 9am status meeting: Three supports over the last day. DSS-54 lost TLM and CMD when the transmitter and antenna died, but they restarted in about 1 minute and all requirements were completed. CAP 893A was run to disable SCS 29 following the end of eclipse season. JAN3105A products were reviewed yesterday. Some small issues were corrected, and the revised JAN3105B products are out for email review to be completed by noon today. Thermal working group yesterday discussed increase of FSS and ACIS limits. See http://occweb.cfa.harvard.edu/occweb/web/fot_web/eng/working_groups/thermal/twgindex.htm for Tan's presentation. ACIS focal plane cooling test last Saturday was not successful. Temperature only reached -120.5. Team is looking into whether the earth was in the radiator field of view. Test will likely be rescheduled during the next long HRC observation. Some non-real-time data was flowed to the CXC/dataops yesterday. Was Caught by dataops in a few minutes an switched off. Conference room is to be decommissioned starting next Monday, Jan 31.
