The Sunspot Solar Observatory (SSO), also known as the Sacramento Peak Observatory, is an astronomical observatory designed for the study of the Sun. In February 2026, the U.S. National Science Foundation announced that the Sunspot Solar Observatory closed to the public indefinitely following the discovery of a mercury leak in the Dunn Solar Telescope.
