              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Skies were partly cloudy at sunset so we opened. Almost immediately the humidity spiked. We pushed limits for a bit, but then the humidity rose to where staying open was not an option for any length of time. Fog came in at 20:30. Fog came and went all night. We gave up at 06:00.
