Observing Summary:

At first we couldn't believe it.  It must be a sucker hole.  A
HUGE sucker hole.  But it remained clear throughout the night
with only some thin clouds passing by now and then.  We seem to 
have gotten some pretty good data.

There seem to have been some condensation forming on the window,
which resulted in all of our images having a sun-like image in 
the center.  Since it melted throughout the night it will be 
difficult to try to reduce it from our images.
