 Observing Specialist: J.Dembicky
Spicam temp at start of night 173.1K
Spicam temp at end of night 166.8K
Pointing was off a bit on the telescope.  I corrected it (-90 in XTiltCoef and -650 in YTiltCoef).
Due to Dust I did not open the louvers or turn the fans on until around 02:15.
No problems with drives tonight.  We closed for a little while during the first half due to wind
and dust.  Elevated Dust levels most of the night.
