Observing Summary:

Clouded up before dinner, but there was a hole early in the night
extensive enough to get some good data.  Then it clouded over
and eventually the humidity came up.  It cleared late, and 
humidity dipped briefly; opened for a half-hour and closed up
again just before twilight when it became clear the humidity 
was going back up.  Tonight was supposed to be good, and it was
bad; last night was supposed to be bad, and it was good!
