              ------------- ACTIVITY LOG --------------
Observing Specialist: T.Rudyk
Night started out with a humidity spike that prevented us opening right away. Humidity subsided enough by 22:00 that we decided to risk an opening. Had a humidity scare at 01:32, but the humidity backed off quite quickly after we closed.  We cautiously opened again at 02:01. Humidity dropped off after that, we were in the clear. (See what I did there?)
Observer was able to observe until dawn.
