              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Dcam was having fits of scrambled data around 20:30. (d160-d170 as an example).  Skies were mostly clear.  Skies stayed clear, but the humidity slowly rose over the night, and began to spike around 05:30. Humidity toed the line, and we stayed open until dawn.
