              ------------- ACTIVITY LOG --------------
Observing Specialist: A.Shugart
Great seeing throughout the first half of the night. More spicam darks
taken. We closed at 02:33 due to a massive humidity spike. Conditions only
got worse as the night went on. Assured that conditions weren't going to
change before sunrise, we gave up at 05:20.
