              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
The thunderstorms died down at sunset and things were actually clear! For a little bit. Then the humidity came on strong and we were over 90% until near switch over. Once the humidity let up enough, we were able to open but then clouds started coming in. We closed at 04:08 due to clouds but then...they totally cleared up again only 50 min later! So we were able to get a little more time on sky.
No problems tonight.
