              ------------- ACTIVITY LOG --------------
Observing Specialist: C.Gray
We had virga all around us at the start of the night but it only delayed out opening by a few min. WY02 was able to get some data, though it was poor and through thick clouds. Things started getting dicey with nearby radar returns so I closed the dome during switch over to UW07. We were not able to reopen, but it actually didn't start raining until 2am. Things were still completely clouded over and damp by 4am with winds gusting over 35 mph so I called it.
No problems tonight.
