              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
We started with partly cloudy skies (but also hazy). Wind was calm. We opened after observer finished their cals. Skies stayed clear but with a thin haze. Wind turned west around midnight, seeing improved. Occasional clouds plagued us but we did not close down. We were open all night.
