There are few solar surface brightness observations with sufficient accuracy to have direct bearing on the question of the origin of the Sun’s bolometric luminosity and irradiance changes (the correlative observations have been reviewed elsewhere in these proceedings). This paper contrasts these observations with a model for the solar variability and illustrates our clear need for high precision surface photometry, in combination with helioseismic data and numerical experiments.
