Synoptic Optical Long-term Investigations of the Sun (SOLIS) is a new 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).
SOLIS will provide unique observations of the Sun on a continuing basis for several decades to understand the solar activity cycle, sudden energy releases in the solar atmosphere, and solar irradiance changes and their relationship to global change.
SOLIS is composed of a single equatorial mount (right) carrying three telescopes. The first system is located on top of the Kitt Peak Vacuum Telescope building (left), and the NSO Long Range Plan calls for a global network of two more VSMs to enable continuous solar observations.
