MDM Observatory 1.3m Telescope Observing Report for 2018 Apr 20

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

Instrument: Templeton

Worked for 10 hours (most of the night)
Conditions were Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Seeing 2.0 arcsec, Clear, Winds Moderate
   Mid: Seeing 1.8 arcsec, Clear, Winds Moderate
   End: Seeing 1.8 arcsec, Clear, Winds Light & Variable

Observing Summary:

An excellent night, photometric with good seeing and tracking,
stable temperature.

Pointing away from the wind, which had shifted from previous
nights, may have helped.  A couple of times the telescope 
had a high-frequency oscillation in the E-W direction, but it
only lasted a couple of minutes.  It was faster than the
1 second exposure time of the guide camera.
