MDM Observatory 1.3m Telescope Observer's Report for 2007 Jan 13

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

Instrument: Templeton Direct

Worked for 7 hours (off and on through the night)
Conditions were Non-Photometric most of the night.
Problems were encountered, see the separate trouble report for details.

Seeing and Weather:
   Clouds all night.
   Beg: Seeing 3 arcsec, Patchy Clouds, Winds Moderate
   Mid: Seeing 4 arcsec, Patchy Clouds, Winds Moderate
   End: Seeing 2 arcsec, Clear, Winds Moderate

Observing Summary:

Overcast until 9pm.  Then clouds on and off, largely disappearing
after midnight.  In the first part of the night, brief time series
of a couple of CVs were largely useless.  But a four-hour run
on the blazar 3C 279 at the end of the night was quite nice.
Except for a problem with the filter wheel (see trouble report
to follow).
