MDM Observatory 2.4m Telescope Observer's Report for 2001 May 27

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

Instrument: CCDS

Worked for 1 hours (last half of the night)
Conditions were Overcast most of the night.
No equipment or software problems were encountered.

Seeing and Weather:
   Clouds from 17:00 until 3:30.
   Beg: Overcast, Winds Light & Variable
   Mid: Overcast, Winds Moderate
   End: Seeing 4-5 arcsec, Cirrus, Winds Moderate

Observing Summary:

Thick cirrus and clouds covered the entire sky at sunset.
At 1:30am it seemed to clear from the West, so I opened up
and prepared to observe, but the cirrus was still to too
thick in general (but variable at times) to observe and it
then got worse again. So I closed half hour later. 
At 3:20am it started to clear and so I opened up again. The 
cirrus thinned and I could observe, though there was still 
very thin, variable cirrus. The seeing was really bad and 
it is unlikely that the data will be particularly useful.
