Observing Summary:

Remarkable night - cleared very rapidly around sunset, and 
humidity dropped quickly. There were a few clouds early on
but it became very clear. Temperature increased slightly through
the night, too.  

Weirdly, the dome started working again!  We had done a lightning
shutdown in the afternoon, and we didn't notice when it actually
started working again, but partway through the night when moving
the dome manually we noticed that the correct azimuth was being
displayed. It seems likely that rebooting the TCS machine
made something work again, but that's unproven of course. 

One glitch regarding the 1.3m -- we attempted to purge the 
dewar window at the start, but even though the lucite flow
meter was registering, there didn't seem to be anything 
coming out of the end of the hose.  The hose may have a crack
in it somewhere.
