MDM Observatory 2.4m Telescope Observer's Report for 2008 Jun 02

Observer(s): McGreer
Institution(s): Columbia

Instrument: CCDS

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

Seeing and Weather:
   Beg: Seeing 1.5 arcsec, Clear, Winds Light & Variable
   Mid: Seeing 1.3 arcsec, Clear, Winds Moderate
   End: Seeing 1.3 arcsec, Clear, Winds Light & Variable

Observing Summary:


Nice observing overall, acquired spectra of a transient 
and several radio quasars.  No significant problems, however,
in bias and other low-signal images CCDS shows diagonal striping
across the image.  I originally thought this was due to the
warm weather in the afternoon (~26C), but it persisted throughout
the night.  I see in the manual this is a known problem so I will
just note it here.
