              ------------- ACTIVITY LOG --------------
Observing Specialist: D.DeColibus
Overcast at the beginning of the night, with rain and thunderstorms arriving around 8:30 PM. The rain didn't last too long, but the clouds persisted and were too thick to be worth opening.
The clouds slowly dissipated enough that we opened at 12:30 AM, getting about an hour of usable skies. But clouds kept forming over us after 1:30 intermittently. They finally cleared up a decent amount after 3:30.
No problems tonight.
