MDM Observatory 1.3m Telescope Observing Report for 2011 Dec 28

Observer(s): Halpern, McCarrick, Gordon
Institution(s): Columbia U.

Instrument: CCDS

Worked for 8 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 Moderate
   Mid: Seeing 1.5 arcsec, Clear, Winds Moderate
   End: Clear, Winds Moderate

Observing Summary:

I parked the rental car at the 12m radio telescope
in order not to interfere with the power company
digging in the road, which leaves just barely
room to squeeze past into MDM.  I hope that's okay.

This was the last night of a very productive run,
despite some pointing problems in the far north.

In the past 24 hours the dewar started to warm up
a couple of times.  Possibly this is due to incomplete
filling, but in any case the dewar will have to be
pumped for its next run.

I'm doing some dome flats now.  They seem to be working.
We'll see after reducing the spectra.
