Instrument: CCDS and Retrocam

Worked for 12 hours (all night)
Conditions were Non-Photometric most of the night.
No equipment or software problems were encountered.

   Mid: Seeing 1 arcsec, Clear, Winds Calm
   End: Seeing 1 arcsec, Clear, Winds Calm

Observing Summary:

I haven't remembered to mention it, but the CCDS readout pattern
that had disappeared for a time has been present since I started
my run.  I'll just mention again what has been said before.  The
effect is quite dramatically bad when observing a faint 
supernova.  The readout pattern can erroneously be interpreted 
as supernova spectral features.  And the time variation makes it
difficult to remove during reduction.

I observed five SDSS supernovae, the CV we've been following, 
two supernova from the Carnegie Supernova Program, three of C.
Kochanek's lenses, and SN2006jc.  The clouds were better in than
they have been in the last few nights, just sticking around the
horizon.
