The UC12 time was donated to Mike Strauss, as agreed upon by the site manager. (An agreement had been made to arrange for images taken with SPICAM to be donated to the UC12 project for the time). Mike Strauss, Zeljko Ivezic, and Chris Stubbs all participated in the PU02 run. They were able to take twilight flats, but a storm front moved in around 21:20, and caused us to close the telescope. The sky became completely overcast, and the dewpoint quickly increased. The dewpoint continued to fluctuate until 1:00, when the sky finally cleared. We reopened at this time, and Michael proceeded with the help of Chris. The skies stayed hazy for the rest of the evening.
