Observing Specialist: T.Rudyk
Thunderstorm in the afternoon which thankfully blew out by dusk. We opened at sunset. Winds were calm, seeing was ok, but the haze from smoke was still around. Winds increased around 21:00 and seeing degraded somewhat. Got better again after midnight. It stayed clear the rest of the night. We were open all night.
