              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started partly cloudy, but there was a storm headed our way (on radar and visually verified) from the north that prevented us opening at dusk. The storm narrowly missed us, and nothing else was coming our way, so we opened. It cleared up, winds were calm, and seeing was very good. We were open the rest of the night.
