              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started partly cloudy, but with rain headed up from El Paso. We stayed closed until it passed. We opened at 00:35 when radar was clear, but it was still too cloudy to observe. It finally cleared out around 01:40. Stayed clear the rest of the night, and we stayed open until dawn.
