              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started partly cloudy, but the  weather grew increasingly unstable, with very localized rain in the area. There was a front moving toward us quickly, but some clear sky opened up ahead of it. The clear sky stayed with us, and the system coming toward us fell apart. Skies stayed clear with good seeing until dawn.
