              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started out mostly cloudy, but the clouds seemed thin enough to punch through.  Since there was no dager of rain, we opened and attempted some science.  Clouds were thin enough to observe through, but the skies would certainly not be called photometric.
Things began to improve around 04:00, with only thin high clouds remaining, and continued to improve thorugh dawn.
