              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started with high thin clouds and so-so seeing. Clouds began to thicken around 21:00 but brought better seeing.
Another wall of clouds hit around 01:00, increasing in thickness. A line of rain formed on the radar around 3:00, heading for us. We had to quickly close by 03:38. We did not open after that.
