MDM Observatory 1.3m Telescope Observing Report for 2009 Jun 20

Observer(s): Parks, Terndrup
Institution(s): OSU

Instrument: 4k

Worked for 5 hours (last half of the night)
Conditions were Mixed most of the night.
Problems were encountered, see the separate trouble report for details.

Seeing and Weather:
   Clouds from 7 until 11:30.
   Beg: Seeing NA arcsec, Overcast, Winds Light & Variable
   Mid: Seeing 3.5 arcsec, Patchy Clouds, Winds Moderate
   End: Seeing 1.5 arcsec, Clear, Winds Calm

Observing Summary:

I was unable to observe for the beginning of the night due to cloud
cover and the threat of rain, however around 11:30 it began to clear
up.  I began taking data at 7:17 UTC with good focus, but the seeing
was very bad (~3.5 ).  The first few hours were slow since I had to 
constantly change targets depending on cloud cover and also wind 
was an issue for a short period of time.  As the night went on
things began running more smoothly and the seeing continued to 
improve.  By the end of the night, seeing was consistently around
1.5 .  There were a few exposures where clouds crept in and 
therefore guiding did not function properly, but other than that
guiding worked ok.
