              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started with clouds and scattered showers passing through. We attempted an opening around 21:45, but the clouds were too thick to even allow a focus, then the rain began to return on the radar, so we closed shortly after. It started to clear around 01:10 and we tried opening again, this time had much better results. We stayed open until the dawn.
