Routine Operations
· RBI clock resync every ~194 days
­ One on July 21th 2008 ­ Other on January 1st 2009.

· Eclipse season fully nominal.
­ 19 earth eclipses plus 4 lunar eclipses.

· And, of course, a lot of nominal observations performed

Routine Operations
· Autocommanding is operational
· Since October 14th, Rev 1651

· Mostly for safe in case of radiation · The machine follow the same procedures that the {human} space craft operator · So no change in what is done, but in who do it. · Some `new thing' fixed were needed

New ODBs from 6.0 to 6.5
· No significant changes for EPICs · Includes :
­ ­ ­ ­ ­ New hot stuff for MOS (offset tables) Refinements to PN Mosaic mode Fixes to MOS 3x3 Offset calculation Autocommanding fixes Simplification of spacon work ...

New Hot Stuff
· New versions of the MOS Offset Tables
­ Now at version V13

· Changes in place since Revolution 1690 (March 1st )

MOSAIC observation mode
· Offered in AO-8 (current one). · EPICs are ready
· New mode for PN:
­ Calculate the offset tables in slow mode (100 repetitions) and with the FW=Closed Closed ­ Then observe continuously (with the requested filter) when the S/C move from a pointing of the mosaic to the next one, and so on.
OFFSET FW X OBS MODE FW X OFFSET FW X OBS MODE FW X OFFSET FW CLOSE

OBS MODE FW X

· MOS do not need operational modifications, impact only at Mission Planning level.

MOS 3x3 OFFSET
· Done on 4
th

July, once the new ODB items were available

· Offsets and Variance calculated on board by MOS instruments with settings set for 3x3 mode, followed by an small observation making use of these offsets. · Previous offset calculation performed in 2000, and was in 1x1 mode only · The until now only available 3x3 offsets were theoretically derived by T. Abbey back in 2006 · Results
­ Obs ID 9156900005 (slew 5 into rev 1569) ­ Obtained the Offset and Variance tables for all CCDs ­ Plus a Full Frame 3x3 image using these offsets (FW=Closed) XMM-Newton

MOS Timing Diagnostics
· Done on 29th May, partially successful. · Only tried 2 other times on the mission (2001 and 2005), and the last failed. · Today Timing configuration is different than in 2001, so no direct comparison is possible. Thus this time was performed with the old and the current configuration. · The instruments work as expected (raw TLM recovered) but the ground control system only was able to process a few as exposures. · Result:
­ Rev 1551, Obs_id 0551761101 XMM-Newton

MOS 2 EMCR SW crash
· · · · On Feb 23th EMCR sw changed to ROM Second time in history (first in 2002) At that time it was in Idle, FW=Closed Was just at the end of the Radiation Belts passage.

· Smooth recovery, no science lost.

ESAM and RF lost
· · · ESAM from 6th to 9th October RF lost from 18th to 22th October (inst rec 24th) The EPICS were in perigee configuration when happened (Idle mode, filter wheel Closed), and changed shortly after to Safe Stand-by mode.

· CCD temperatures were controlled and stable all the time. · Electronic boxes temps reached -6.4 °C · Recover after heating up, without problems on the instruments · PN recovery procedure need a fix (not used since years ago) · No impact was seen in subsequent CAL observations
