              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Evening started out cloudy and humid, we were not able to open.  Clouds dispersed somewhat around 18:00, but humidity remained high. Humidity started to drop after midnight, we were able to open at 00:51. As soon as we did, humidity started to spike again, and we closed at 01:20. We were unable to open the rest of the night due to humidity, and clouds kept rolling in getting thicker until AP01 called it a loss.
