MDM Observatory 1.3m Telescope Observing Report for 2014 Sep 19

Observer(s): Halpern, Alford, Borgman
Institution(s): Columbia

Instrument: Templeton

Worked for 9.5 hours (all 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 1.2 arcsec, Cirrus, Winds Calm
   Mid: Seeing 1.2 arcsec, Clear, Winds Calm
   End: Seeing 1.2 arcsec, Patchy Clouds, Winds Calm

Observing Summary:

This is the first night used on the 1.3m this semester.
About 1/2 hour after sunset conditions were suitable for opening.
Initial pointing was accurate to 3 arcminutes, and was zeroed
on a bright star.  We then had to use about 30 minutes of dry
nitrogen to clear a drop of condensation.  With no wind and good
seeing, tracking was excellent.  Clouds came back around 4am.
The only minor problem concerns an inaccurate clock time on
mdmarc2, which writes the time to the headers of the data files.
