              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
Hey, no problems today due to the hub work! I can confirm that the weather page reads the dome door as open when it is open. Which, frankly, I'm surprised we opened tonight. We had rain and complete cloud cover for A half. However, at 2:21am, things cleared up enough and the humidity was safe enough to open. We were able to stay open until 5am when the humidity spiked. We did not reopen.
No problems tonight.
