              ------------- ACTIVITY LOG --------------
Observing Specialist:    J.Dembicky
We had some clouds and wind gusts during evening twilight that kept us closed.
A very nice lunar eclipse tonight, despite some pesky clouds during egress.
Clouds during most of tonight (well, we had somewhat clearer weather during the eclipse) and then
they rolled back in at twilight (and the humidity went up as well).
