On egress, do obsid 6975, an 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.

NOTES/ISSUES/PROBLEMS SOT snapshot is not updating. From the 9am status meeting: Ten supports over the weekend, 3 issues: JPL lost TLM and CMD for 38 minutes, cleared by swap back to primary SFG; DSS-66 had too many CFC increments, reset and resent data; JPL had no TLM due to misconfiguration of the SFG, used COG #2 for TLM. CAP 425F was run successfully to execute the monthly EIA sequencer self-test. CAP 1001 was run successfully to dump and clear all the EPS glitch counters. Three segments of the JUL1006B loads were uplinked. On-board loads are good until 195:04:00. The JUL1706A products were circulated last Friday, load review at 2pm today on 1165# Second of current eclipse series occured Friday, ran nominally except that the glitch counter incremented on the battery disconnect circuit. This has happened before and is believed to be a timing issue, and not a concern. The third eclipse occured earlier today, apparently nominal subject to data review. ACE soft proton rates are in the few 1000's. Highest in a long time, but still at least 10 times below levels of concern. Expected from CME on July 6. The ACIS parameter block was not commanded for obsid 7292. This was a calibration observation of PKS2155-304, using ACIS-S/LETG. Parameter block used was an event histogram and the observation will not be useful. Issue is tracked to 2 independent human errors: the parameter blocks for ACIS next in line mode needs to be manually inserted, and since OFLS does not know about this it needs to be told that ACIS doesn't have the correct pBlock already loaded (and this didn't happen for this one observation -- several others were done correctly); in addition, this was missed in the ACIS load review process. The ACIS load review software is already in process of revision to track the on-board parameter blocks (and other status) more automatically.
