Observing Specialist: McMillan
The enemy tonight was humidity bouncing around near the limit,
especially when the telescope was open long enough to be colder than
the air.  We were open from 22:30 to 00:10, and then from 00:40 to
02:00.  Seeing was excellent while we were open, perhaps approaching
half an arcsecond, but because of the borderline conditions we never
spent too much time fine-tuning the focus.  We also had two failures
of the GRIM application during first half, and several "no flush"
errors.
