Several radio sources are located within the 90 percent confidence limit of the strong, unresolved gamma-ray source CG 195+04. For the best radio candidate 0630+180, a quasar at z = 1.2, the third such object found to lie within a COS B error circle, is optically identified. If the QSO 0630+180 really were associated with CG 195+04, it would be the most luminous source of high-energy photons known. If its luminosity is due to proton enhancement, this may be the first step toward identifying a potential source of the nucleonic component of cosmic rays.
