Do obsid 7367, another piece of the long ACIS-S observation of the distant (z=1.4), massive cluster of galaxies XMMU J2235.3-2557, jointly with XMM to use the structural properties to confront to evolutionary and cosmological scenarios.

EPH temp: 98.62 degF EPH 27V: 14.76 NOTES/ISSUES/PROBLEMS From the 9am status meeting: Three supports over the last 24 hours, no issues. One stored command segment uplinked, on-board loads good until 196:22:10. 1706B products were reviewed yesterday with no issues. They have now been approved and signed-off by the Flight Director. Three test loads are out for review, comments requested by noon tomorrow, Thursday. These are for support of the OFLS 11.6.1 promotion. ACE solar proton rates are back down to a few times background. Sun is expected to be very quiet over the next days. Preliminary results of the recent ACIS focal plane cooling test show 2.5 deg C margin against the -119.9 deg set point. This is at most a 1 degC degradation of capability since early in the mission, and bodes well for being able to maintain the set point many more years into the future.
