Lowell Observatory comparing these measurements with a reference set of Sun-like stars. Lowell Observatory is building a major new reflecting telescope in partnership with Discovery Communications, located near Happy Jack, Arizona. This Discovery Channel Telescope (DCT), located within the Mogollon Rim Ranger District of the Coconino National Forest, is expected to be the fifth-largest telescope in the contiguous United States, and it will enable the astronomers of Lowell Observatory to enter new research areas deeper into outer space. The DCT and the research carried out there will be the focus of ongoing informative and educational television programs about astronomy, the sciences, and
United States Naval Observatory Flagstaff Station complex. Attached to its large "hut" is the building housing NOFS' electronics and electrical engineering laboratories and clean rooms, where most of the advanced camera electronics, cryogenics and telescope control drives are developed and made. NOFS operates the Navy Precision Optical Interferometer (NPOI) in collaboration with Lowell Observatory and the Naval Research Laboratory at Anderson Mesa, south-east of Flagstaff. NOFS (the operational astrometric arm of USNO) funds all principle operations, and from this contracts Lowell Observatory to maintain the Anderson Mesa facility and make the observations necessary for NOFS to conduct the primary astrometric science.
