MDM Observatory 2.4m Telescope Observer's Report for 2007 Jun 22

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

Instrument: echelle CCD direct + 2in FW

Worked for 9 hours (all night)
Conditions were Photometric most of the night.
No equipment or software problems were encountered.

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

Observing Summary:

A fine night, mostly, photometric all night.  Seeing was highly
variable, with long stretches of very good seeing down to 0.7 
arcsec at times and patches of poor seeing interspersed.  A 
bubble of air with more-than-zero humidity came over -- not a 
cause for concern, but the mix of different humidity and temp
seemed to affect the seeing.  

The dome returned to the contacts within a few inches at the end
of the night, much closer than the previous two and enough to 
make electrical contact without any adjustment.
