Show moreThe purpose of this investigation was to obtain some quantitative information about the gradient of the sky brightness near the Sun. This information was needed to make preliminary computations of the possibility of detecting the K corona, at various distances from the limb, by measuring the polarization of the light which forms the first image in the coronagraph.
