Two-dimensional Photometry of Active RegionsA set of two dimensional photometric images of solar active regions (AR's) are described. Preliminary analysis of the data is described, and estimates are presented of the contribution of an AR to total solar irradiance variations during its 1982 August 3 to 16 disk passage. Results indicate an excess contribution near the limb and a deficit away from the limb. Also apparent is an evolutionary change in the AR which is represented as a decrease in sunspot area.
