No equipment or software problems were encountered.

Observing Summary:

Another successful night of CV spectra.  Spent most of the night 
hitting 3 targets for hour-long stints, until the dewar window 
had condensation on it.  I didn't diagnose the problem quick 
enough, so the continua on about an hour's worth of data are 
not accurate; we may be able to get some RVs out of them though.

I flushed the dewar window with dry nitrogen for 20 minutes, 
and that cleared up the problem. Unfortunately, the night was over 
by the time this was done. Oh well...there's always tomorrow.
