Summary
----------------------------------------------------------------------


- Another remarkably stable, photometric, beautiful sub-arcsec night
with even 0.5" DIMM periodically seeing.

- Unfortunately lost most of the night due to a tracker gear-box failure.
The fix by tech.ops will be installed during the day.

- Succesfull UV T Pyx spectropolarimetry just before that.

- Lots of F-P calibrations - burned out a Ne lamp in the process.
