MDM Observatory 2.4m Telescope Observer's Report for 2007 Jun 29

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

Instrument: Modspec + echelle CCD

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 1+ arcsec, Clear, Winds Moderate
   Mid: Seeing 0.9 arcsec, Clear, Winds Calm
   End: Seeing 0.9 arcsec, Clear, Winds Calm

Observing Summary:

Another fine night, no problems with the equipment.  Winds kicked
up a bit in the afternoon, and seeing was mediocre as the 
temperature dropped after sunset, but things settled down nicely
after a while.  Full moon, but fortunately I had targets that were
bright enough to stand it.  Some cloud far to south at sunset, 
but they never got here, and with this moon I would have noticed
any cloud at all.

As always with spectroscopy, the seeing is nothing but a guess.
