MDM Observatory 1.3m Telescope Observing Report for 2017 Dec 20

Observer(s): Jules Halpern
Institution(s): Columbia U

Instrument: Templeton

Worked for 9.5 hours (most of the night)
Conditions were Non-Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Seeing 2 arcsec, Clear, Winds Moderate
   Mid: Seeing 2 arcsec, Clear, Winds High
   End: Clear, Winds High

Observing Summary:

The classic N-S oscillation began almost immediately,
even though the telescope was pointed north, away from the wind.
Wind shake became nearly constant after midnight, when
pointed to the south.  Closed early because of this. 

Main dome slit would not close.  Had to stop and
start the telescope program to get it to close.
