              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Weather started mostly clear, but with the threat of storms moving in.  We opened at sunset. By 21:12 storms were popping up nearer to us and humidity had spiked, so we closed. Humidity remained too high to open for the rest of the night.
