MDM Observatory 2.4m Telescope Observer's Report for 2008 Sep 01

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

Instrument: modspec + echelle CCD

Worked for 10 hours (all night)
Conditions were Mixed most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Seeing 1 arcsec, Patchy Clouds, Winds Light & Variable
   Mid: Seeing 1 arcsec, Clear, Winds Light & Variable
   End: Clear, Winds Light & Variable

Observing Summary:

Finally, a very good night.  Fair-weather cumulus yesterday
afternoon, a few isolated rain storms, a little bit of thunder
in the distance, but much less Sturm und Drang than the previous
days.  Settled down more and more toward sunset, and was usable
from the start.  By the end of the night it was photometric with
good seeing!  Got quite a bit done.

Becuase of the run of poor weather I'd like to keep the 
spectrograph on for one more night and switch to direct on 
Wednesday, unless this creates staffing difficulties.
