MDM Observatory 2.4m Telescope Observer's Report for 2006 Jun 22

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

Instrument: modspec + echelle CCD

Worked for 5 hours (off and on through the night)
Conditions were Mixed most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Seeing 1 arcsec, Clear, Winds Light & Variable
   Mid: Seeing 1.5 arcsec, Patchy Clouds, Winds Light & Variable
   End: Seeing 1.5 arcsec, Overcast, Winds Light & Variable

Observing Summary:

Very cloudy afternoon, but it cleared off nicely before sunset and
was pretty good for a few hours.  Daytime temps had been 
suppressed by the clouds, so the dome and telescope equilibriated
easily and the seeing was decent at the start.  Later at night
variable high cloud came in, always in the way and sometimes
completely thick.  Closed around 1:00 and reopened around 2:40
when conditions were somewhat better; after a few exposures it 
got thick again, and it was time to button it up for good.

This has been a very successful run; many thanks to Bob, Tony,
and Paul for their help.
