              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started clear and calm. Seeing was not great. Around 21:00 a front passed through, with clouds and rain popped up on the radar, so we closed. We opened again after the threat of rain passed around 23:00. Seeing had improved somewhat, and it stayed clear.
