The sky was clear all night, but it was windy. The telescope was closed for wind at 01:00 MDT, reopened at 3:30 and closed at 04:10 for the remainder of the night. I observed for PU01 and obtained some good images of two gravitational lens systems. Jon Holtzman and Salman Hammeed were on-site to observe for NM06. This run went ok, although the guide camera didn't have a very good star to work with and the wind may have been buffeting the telescope. Brooke Skelton observed remotely for UW07. We were shut due to high wind most of her time. She got a few images in, but lost some time because I had the filters listed in the wrong order in the text file.
