Yuba City Astronomical Observatory is a private observatory south of Yuba City, California, near the Sutter Buttes. Owned by the Doscher Family Trust and operated primarily by trustee Richard J. Doscher, it was established on September 22, 2010. Its main instrument is an 11-inch Schmidt-Cassegrain telescope on a permanent pier inside a 9-foot dome. Work at the facility includes planetary observing, deep-sky studies, near-Earth object research, astrometry, photometry, and astrophotography. The observatory’s IAU/MPC assignment number remains pending.
