Observer(s): Christoper Carroll
Institution(s): Dartmouth College

Worked for 6 hours (first half of the night)
Conditions were Photometric most of the night.
Problems were encountered, see the separate trouble report for details.

Seeing and Weather:
   High Humidity all night.
   Beg: Seeing 0.9 arcsec, Clear, Winds Calm
   Mid: Seeing n0.9 arcsec, Clear, Winds Calm

Observing Summary:

I started the night with sub-arcsecond seeing, but noticed the humidity starting 
to rise early. I attempted one target but noticed the guide probe was not holding
the target steady. After attempting to fix the issue, I lost pointing and had to 
manually restore the RA/Dec encoders. I returned to observing but the humidity 
climbed into the red (90%) and I closed down.
