MDM Observatory 2.4m Telescope Observing Report for 2010 Mar 25

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

Instrument: Modspec + Echelle CCD

Worked for 11 hours (all night)
Conditions were Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Seeing 1 arcsec, Clear, Winds Light & Variable
   Mid: Seeing 0.9 arcsec, Clear, Winds Moderate
   End: Seeing 2 arcsec, Clear, Winds Moderate

Observing Summary:

At last, a good clear night.  Seeing was good most of the night
but deteriorated abruptly at the end as temperature dropped and
the wind picked up.

The Andor camera is vastly superior to the image tubes for slit
viewing, and will make a great guide camera when we get all the 
software to play nicely.
