Abstract

Using two very high resolution, white-light plates of the solar granulation, we measure a characteristic size and intensity for facular points. The plates were obtained with the 50 cm refractor at Pic-du-Midi Observatory using a 60 A bandpass filter center at 5750 A. After adjustment for atmospheric and instrumental smearing, we find a characteristic size of 0.22 arc sec and a characteristic intensity of 1.3 to 1.5 times the mean continuum intensity.
