The 2012 December campaign finishes with a very fine night. There was some light, scattered cirrus in the sky at the beginning of the night, but this cleared off/dissipated quickly. For most of this very stable night, the seeing was 1.5 arcsec or better. Overall, campaign 45 was exceptionally productive. Over 170 polarization measurements were obtained for LAT-monitored blazars.
The 2013 Fermi/Steward Observatory campaigns will begin at the Bok Telescope on January 12 UT. Happy Holidays to all who follow this site!
