Moderate to thick cirrus all night. Amazingly, 9 targets were successfully observed through the muck during the night. This was only possible because the moon was not in the sky. Only the brightest targets could be observed, but 3C 454.3 was one of them. This ends observing campaign 12 and the Steward Observatory observations for Fermi for 2009. We'll pick it up again in 2010 January. Have a happy holiday season.
