Valtonen, M. J. Abstract It is pointed out that (1) the magnitude of the recently discovered optical object, which coincides with component B of radio source Cygnus A, is as expected if the object is physically associated with the radio component and if it is a scaled-up version of a knot in the well-known jet of M87; that (2) the existence of such a knot in component B was previously predicted; and that (3) if two such knots were to be ejected from a galaxy to a distance of about 100 kpc, the resulting radio source would probably look much like Cygnus A. Under the assumption that this ejection took place, the main physical parameters of the radio source are derived. The masses of the supermassive black holes required to power the knots probably exceed 10 to the tenth power solar masses.
