              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started partly cloudy with high winds.  Winds died down for a while around sunset. Winds got a little high after sunset, but not enough to force a close.  By 22:00 the wind was not a worry.  Skies stayed mostly clear, but seeing was so-so. After midnight, seeing improved.  Skies remained clear and the wind was not a problem for us.  We stayed open as long as the observer needed.
