              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started cloudy, but then there was clearing around sunset: part of a large suckerhole. Unfortunately humidity spiked almost immediately. Humidity stayed high and went to fog on occasion. High winds began around 21:00. Winds were topping 45 by 04:00. We called the last program before it began due to winds and high humdiity. We never opened.
