MDM Observatory 2.4m Telescope Observing Report for 2009 May 16

Observer(s): D. Milisavljevic

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

   Beg: Seeing 1.5 arcsec, Clear, Winds Calm
   Mid: Seeing 1.4 arcsec, Clear, Winds Calm

Observing Summary:

A reasonable night overall.  Seeing was poor (> 1.5 arcseconds)
for the first half of the night, but improved later on.  Clouds
and high cirrus visible toward the end of the evening.  I think
they mark the beginning of bad weather to come. :(
