MDM Observatory 2.4m Telescope Observer's Report for 2005 Nov 15

Observer(s): S. Lepine
Institution(s): AMNH

Instrument: Direct + Echelle

Worked for 12 hours (all night)
Conditions were Photometric most of the night.
Problems were encountered, see the separate trouble report for details.

Seeing and Weather:
   Beg: Seeing 2.5 arcsec, Clear, Winds Moderate
   Mid: Seeing 1.2 arcsec, Clear, Winds Light & Variable
   End: Seeing 1.1 arcsec, Clear, Winds Light & Variable

Observing Summary:

Night started with very bad seeing which I suspect may
have occurred because of a warm secondary mirror (8 degrees 
Celsius above ambient). But then perhaps it was the wind. 
Seeing stabilized around 1.2  after a few hours (as the 
secondary cooled down). Conditions were then excellent for 
the rest of the night.

At closing, two of the mirror cover petals (North & South) 
wouldn't close. They are still open at this time.
