   End: Cirrus, Winds Light & Variable, Closed.

Observing Summary:

Full moon!  Started out clear with light wind and very good
seeing -- below 1.5 arcsec, which is good for the 1.3m -- and
very good conditions held for a couple of hours.  Then, light 
cirrus started coming in from the southwest. These were fairly 
transparent but scattered quite a bit of moonlight, raising the
already strong background. Some clearer patches blew over, 
so I kept going until my principal target was way over in the 
west. By then the cirrus were heavier, and the IR images on the 
College of DuPage site showed still thicker cirrus coming in, 
so I closed up and called it a night.
