MDM Observatory 1.3m Telescope Observing Report for 2015 Jun 24

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

Instrument: Templeton

Worked for 2.5 hours (first half of the night)
Conditions were Non-Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Seeing 1.5 arcsec, Patchy Clouds, Winds Light & Variable
   Mid: Overcast, Winds Light & Variable
   End: Overcast, Winds Light & Variable

Observing Summary:

Opening was delayed until just after 9pm, when the clouds thinned
out enough.  The first thing I did was to zero the pointing on a
bright star near zenith.  I verified that the true zenith values
of the tilt meters posted on the window a couple of years ago are
still valid.

After observing the first target for about 20 minutes, problems
occurred which I traced to power cables becoming loose for the
filter wheel and the guide camera (see separate trouble report).

A moaning sound from the telescope noted a couple of nights ago
is present most of the time.

I closed at 11:30pm when more clouds came in, my hopes for
getting a long time series during this run dashed.
