              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Conditions were partly cloudy at the start of the night, but no radar returns, so we opened at sunset. By 22:00 most of the clouds had blown out except for the occasional high thin clouds. The night remained the same until dawn, and all programs got all their full time in.
