Commentary Relative to the Distribution of Gamma-Ray Flares on the Sun: Further Evidence for a Distinct Solar Surface

High energy gamma-ray flares are almost always observed near the limb of the Sun and are seldom, if ever, visualized in the central region of the solar disc. As such, they exhibit a powerful anisotropy best explained by invoking a true photospheric surface. In this regard, the anisotropic nature of the gamma-ray emissions from high-energy flares constitute the eighteenth line of evidence that the Sun is condensed matter.
