MDM Observatory 2.4m Telescope Observing Report for 2011 Mar 20

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

Instrument: Modspec+Templeton CCD

Worked for 7 hours (most of the night)
Conditions were Mixed most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   High Winds from 20:00 until end.
   Beg: Seeing 1+ arcsec, Cirrus, Winds Moderate
   Mid: Seeing 2+ arcsec, Clear, Winds High
   End: Clear, Winds Above Limit

Observing Summary:

Windy.  Cirrusy at start, then cleared off after sunset (hones!),
then winds picked up and it got cirrusy again -- at that point 
I closed for an hour or so -- and then it cleared again, but 
still very windy.  I kept the louvers closed and worked in
the north, away from the southerly wind.  Wind started to gust
above 40, rarely, then a little more frequently.  Around 3 I
thought to check for dust and found it to be a little too much
for comfort, so I decided to call it a night, since winds are
forecast to keep increasing into the daytime.
