MDM Observatory 2.4m Telescope Observing Report for 2014 Jan 27

Observer(s): John Thorstensen
Institution(s): Dartmouth

Instrument: modspec + Echelle CCD

Worked for 4 hours (off and on through the night)
Conditions were Mixed most of the night.
Problems were encountered, see the separate trouble report for details.

Seeing and Weather:
   Clouds from 10 PM until 5 AM.
   Beg: Seeing 1 arcsec, Patchy Clouds, Winds Calm
   Mid: Overcast, Winds Calm
   End: Seeing 1.5 arcsec, Clear, Winds Calm

Observing Summary:

Beautifully clear yesterday, but cirrus coming in around 
dinnertime; tolerable for first few hours, but clouded up
heavily around 10 PM, as a great swatch of clouds pressed
across the region.  Trailing edge of the system finally got 
here about 5 AM, so I opened again and got a little more data, 
including spectra of the M82 supernova, which is not exactly
a challenging object to find. It was very clear overhead in 
twilight - the clouds had pushed on east.

Troubles, unfortunately - the shutter didn't work, at least
at first.  See report.
