MDM Observatory 2.4m Telescope Observer's Report for 2008 Mar 02

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

Instrument: Modspec + Echelle CCD

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

Seeing and Weather:
   High Winds from start until mid.
   Beg: Seeing 2-3 arcsec, Clear, Winds High
   Mid: Seeing 2 arcsec, Clear, Winds High
   End: Seeing 1.5 arcsec, Clear, Winds Moderate

Observing Summary:

A windy night -- 25 mph at times -- but never approaching the
limit.  The temperature plummetted after dark, going down below
freezing (humidity was very low though) -- consequently, the 
mirror ended up warm compared to ambient.  This plus the wind
contributed to the mediocre seeing.  Nonetheless, I soldiered
on with brighter targets and got some nice results.  Winds 
abated somewhat after midnight and the seeing improved, but 
I had to close a little early to get to the airport.

This has been a very productive run -- thanks to all the staff 
for your support!
