              ------------- ACTIVITY LOG --------------
Observing Specialist : T.Rudyk
Evening started cloudy with the threat of rain. Around 20:00-21:00 we got a suckerhole, it was clear, but there was rain on the radar just a few miles from us, so we stayed closed. Snow began around 03:00.  We did not open at all. The scope was left pointing south.
