    A New CLASS Publication! This OPTICAL CHARACTERIZATION OF THE Q-BAND TELESCOPE required years of careful analysis and is critical to understanding the instrument and data. Check out the very big beam maps and excellent polarization isolation! More at .

    Excited! See the transfer function in this paper (pasted here) demonstrating large-angle recovery. Watch out for more results from the 2-year observations. Next one is tonight on the first detection of circular polarized Zeeman emission from the atmosphere at 40 GHz.

    The four-frequency CLASS survey is officially under way! The team finished up optical alignment of the new 150/220 GHz telescope this weekend. Optics, detectors, modulation all look good so far! Video of telescopes scanning by CLASS-mate

    To learn more about the Jacundá Forest Reserve project, check out 's site , which details how the preservation of rubber trees over the next 30 years will result in 12 million tons of avoided carbon dioxide emissions!

    CLASS is proud to be a CARBON NEUTRAL telescope array. We have purchased carbon credits to offset emissions from powering our telescopes and from travel to our remote observing site. The credits support conservation efforts in the Brazilian Jacundá Forest Reserve.

    What we showed here is that in the Near Future, i.e. by the time finishes its survey (wink wink nudge nudge etc. etc.), its maps will be sensitive enough to rule out alternative models to this star formation process as well as the CMB will EVER be able to do!
