   Mid: Seeing .8 arcsec, Patchy Clouds, Winds Light & Variable, mostly clear
   End: Seeing 1+ arcsec, Patchy Clouds, Winds Light & Variable, mostly clear

Observing Summary:

A tiny, totally isolated cell dropped a little rain on the SW 
ridge while I was up at dinner, judging by the roads, but it was 
long gone by sunset, so I did open.  First couple of hours 
were plagued by nearly stationary high cumulus, but I was
able to work through some holes and it was mostly clear for the
rest of the night.  Nearly calm at first, some light wind at end.
Seeing was pretty good; mighty bright, though.
