It was closed at 22:15 MDT, due to clouds, and reopend at 23:45 MDT. The observers were: myself for PU01, Scott Friedman for JH04, and Rhodri Evans for UC03. My PU01 observations were plagued by clouds, although I did get a few good images. Scott's time was interrupted by the clouds, so he didn't get very much data. The sky was cloudy at the beginning of Rhodri's time, but it cleared off eventually.
