The Sunspot Solar Observatory (SSO) is an astronomical observatory designed for the study of the Sun. The observatory is operated by New Mexico State University (NMSU) and the U.S. National Solar Observatory (NSO). It is split between operations at the telescope facility at Sunspot, New Mexico, and data and management at the Department of Astronomy at New Mexico State University. The Sunspot telescope facility is in the Sacramento Mountains, approximately 18 miles (29 km) south of Cloudcroft. Access to the facility telescopes and grounds are open for to the public for guided tours. It is funded by the National Science Foundation in partnership with the state of New Mexico.
Synoptic Optical Long-term Investigations of the Sun (SOLIS) is a synoptic facility for solar observations over a long time frame that is funded by the National Science Foundation (NSF) and designed and built by the National Solar Observatory (NSO). It is operated by the NSO Integrated Synoptic Program (NISP). SOLIS is a single set of three instruments mounted on a common observing platform. The instruments are the 50 cm aperture Vector Spectromagnetograph (VSM), the 8 mm aperture Integrated Sunlight Spectrometer (ISS), and the 14 cm aperture Full-Disk Patrol (FDP). The VSM telescope is a quasi-Ritchey-Chretien design with a primary mirror operating at f/1.6. The ~ 400 W of solar light from the primary is reflected by a secondary mirror fabricated from a single silicon crystal. The final f/6.6 full-disk solar image is focused on a spectrograph slit that is cooled by a flow of chilled water-propylene glycol solution. The mirrors are coated with protected silver. To improve the internal seeing, the VSM is sealed by 74 cm diameter, 6 mm thick fused silica window. Originally, it was filled with helium at about ambient pressure and temperature. In 2014, helium was replaced by nitrogen due to the increasing cost of helium. Due to this change, the image sharpness was slightly degraded.
Richard Brandner Dunn was an American solar physicist and astronomer who was a pioneer in solar physics. He is known for his designs of solar telescopes and their instruments, most notably the Richard B. Dunn Solar Telescope. At the time of his death he was astronomer emeritus of the National Solar Observatory.
