Observing Specialist: C.Gray
Clouds, clouds, clouds.
Virga, virga, virga.
No hope of opening. UW01 was observing a transit and needed to be on sky by 3:30 am. The moon wasn't even visible, much less stars. And after about 2 am, lots of wind. We gusted up to 40 mph, and the wind wasn't even supposed to start until tomorrow afternoon!
There were email error about the ion pump for arctic, but all was good!
No problems tonight.
