• processing: when it goes well, I can do other things. This week I spent a lot of time figuring out there was high load on ipp049 (high > 100). Not sure what initially caused the high load, but this caused a number of failures on ipp049 in different stages (diff, destreak, dist), and reverting all at once repeated the high load (and failures). Having as few as 28 hosts and reverting all the diffs can reproduce the high load(!). When there are a lot of faults on the same machine, it is necessary to revert only a few of them at a time in order to get those faults corrected.

• finished processing MD01 and MD02, processed MD03 and released all three. Processed MD04 and MD05 through to warp, ThreePi.yz through to camera, and glint for Chris.

• investigated the bad masks & exposures on (2 of them) for the recent MD03 release. All exposures from this were taken near twilight. One image was the last image taken that night, and the background was really high, and was missing many chips in the camera stage (from various twilight issues). The other image had 2 satellite streaks, and many other 'streaks', but no obvious reason why magic went crazy.

• Studied DVO and PSPS database structure in preparation for helping build IPP - PSPS publication system.
• Implemented code to set a couple of required columns in the dvo db.
• Debugged and fixed a couple of ipp tools problems.
• two days vacation to take care of a family member.

• Data Quality statistics code: finished writing dqstatstool and associated scripts. This will allow the data quality information determined by the IPP to be returned to OTIS to aid scheduling.
• Nebulous: installed updated nebulous code in ippdb00 and ippdb02. Looked into outstanding bug for deleting objects with no available instances.
• Sky brightness/moon glints: Looked at the correlation with observed sky brightness with angular separation from the moon. Checked to see how moon glints influence magic streak detection.
