              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Rained until 22:00, then high humidity. The clouds broke around midnight, but it turned out to be a suckerhole that only lasted 15 minutes, then back to clouds. Clouds began to break up around 02:00, but humidity remained high. At that time I did sneak an arcsat opening for 15 minutes so I could test pointing, it is now pointing well.
Humidity remained too high to for the 3.5 to open, even if we were to push the limits. When humidity finally began to drop around 04:30 it was paired with an increase in clouds, such that even the moon was obscurred, so we called it a night.
