MDM Observatory 2.4m Telescope Observer's Report for 2001 May 28

Observer(s): Vestergaard
Institution(s): OSU

Instrument: CCDS

Worked for 8. hours (all night)
Conditions were Photometric most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Beg: Seeing >~2 arcsec, Clear, Winds Light & Variable
   Mid: Seeing ~2 arcsec, Clear, Winds Calm
   End: Seeing ~1.5 arcsec, Clear, Winds Calm

Observing Summary:

It was clear throughout the night, but the seeing was quite
unstable during the first part of the night. Although it
settled down, the stars still stayed somewhat fuzzy (no
centrally concentrated psf could be obtained). At times
the seeing would momentarily get worse even at the end
of the night when it was generally more stable. The primary
mirror warmed up to the temperature of the ambient air 
during the night.
