2.2.0 spase://SMWG/Observatory/SOLIS SOLIS 2019-05-05T12:34:56Z Synoptic Optical Long-term Investigations of the Sun (SOLIS) is a facility at Kitt Peak funded by NSF and designed and built by the National Solar Observatory. It is intended to acquire a multi-decadal (>~25 years) data base for studies of the solar activity cycle, sudden energy releases in the solar atmosphere, and solar irradiance changes. It has three primary instruments, a vector spectromagnetograph (VSM), a full disk patrol (FDP) and an Integrated Sunlight Spectrometer. Data are available between August, 2003 and a few days ago. Both synoptic and user-driven observations are made. spase://SMWG/Person/John.W.Harvey ProjectScientist SOLIS web page at the National Solar Observatory https://solis.nso.edu/0/index.html Earth.Surface
