              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Clouds and fog, clouds and fog. Around 21:00 some rain. There was clearing overhead around 23:30, but groung fog persisted. Skies closed up again by 00:30. Fog blew out around 01:00 but humidity was still high. By 02:00 humidity began to drop, but it was still overcast with precip in the area. We gave up around 05:00. Anticipating precip becoming snow early in the day, the scope was parked due south. We never opened.
