Institution(s): Dartmouth

Instrument: Modspec + echelle

Worked for 10.5 hours (all night)
Conditions were Photometric most of the night.
No equipment or software problems were encountered.

   Beg: Seeing 0.8 arcsec, Clear, Winds Light & Variable
   Mid: Seeing 0.8 arcsec, Clear, Winds Calm

Observing Summary:

Really beautiful night. There was cirrus before sunset, but
it appeared clear all night - nothing obvious on the all-sky
camera.  The big story was the seeing, which was unusually good.
Ambient temperature warmed through the night, and the primary
remained a degree or two below ambient; furthermore, the winds
died down to pretty much nothing.  

Dome was off by a degree at the end of the night.  The yellow
light in the dome auto-enable button doesn't come on when I 
push it (after re-setting dome azimuth on TCS).
