Observing Summary:

Broken low clouds blowing through in the afternoon, clearing 
nicely around sunset - but humidity remained high. Opened during
a somewhat better hour after midnight while Kitt Peak was open,
but then they closed, and our humidity inched upward again, so
I closed up.  Called it around 4:45 AM MST.

No technical problems.  Thanks are due to Rob Fesen, who is on 
site at the 2.4m keeping my dewar cold, and acting as invaluable
eyes and ears.
