MDM Observatory 1.3m Telescope Observing Report for 2016 Mar 06

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

Instrument: Templeton

Worked for 7 hours (most of the night)
Conditions were Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Seeing 1.5 arcsec, Clear, Winds Light & Variable
   Mid: Seeing 1.5 arcsec, Clear, Winds Light & Variable
   End: Clear, Winds Moderate

Observing Summary:

The sky was photometric and observing was excellent until the
humidity rose around midnight.   I closed for high humidity
at 1:45am.

The last science exposure of the night had dozens of bad columns,
something which I had seen a couple of years ago.  However, the
problem went away when I took a couple of bias frames and flat
lamps, so I hope it is was a transient.  I left the offending
image up on the monitor.
