              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Day started partly cloudy, but high humidity. The cloud ceiling was only a few hundred feet above us. As night fell, humidity spiked, and occasional fog was present.
Around 5am humidity started to drop. We opened shortly thereafter. Skies were clear but winds were strong and seeing was bad. We stayed open thereafter until dawn.
