              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started with partly cloudy skies. Around 20:00 an orthographic cloud formed, and hung over a large potion of the sky. It broke up by 22:00, and the sky was clear. Observing was nice and uneventful, with fair seeing.  We stayed open all night.
