Observing Summary:

Another very good night.  Daytime fair-weather cumulus 
dissipated toward evening.  Seeing mostly decent though again
not spectacular.  OSMOS performed well; pattern noise on 
4k seems to come and go a bit, but it could just be the 
scaling on the displays changing.  Simple fill tube did work
OK on 4k.  Squirted some LPS-2 on one of squeaky chairs in the
control room, and it stopped squeaking.
