The Sunphotometer (SPM) is a part of the Variability of Solar Irradiance and Gravity Oscillations (VIRGO) aboard the Solar and Heliospheric Observatory (SOHO). The SPM instrument is composed of a triple sunphotometer with three interference filters (402, 500, and 862 nm) and a silicon photodiode detector measuring the spectral irradiance in the solar continuum.
