              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
A beautiful night!!!  I think November is trying to say sorry about October. Perfectly clear skies, *NO* wind, and I mean none, at one point the gust was listed as 0.5 mph. We had subarcsec seeing basically all night, everyone got all their time, and we were able to catch all the faint targets!  UW05 finished shortly after twilight and I took the opportunity to steal some Venus exposures (because science is more important than sleep when you have a worsening cold?  Or maybe Venus is good for the sinuses? ...VENUS!!!)
Arcsat camera didn't work at the beginning of the night but pulling out the power and USB cables and reconnecting them solved the problem.
No problems tonight.
