Abstract
The presently discussed discovery of weak, high-ionization emission lines in the nuclei of radio galaxies which had been classified as quiescent absorption-line systems demonstrates that AGN-like activity does occur in the central galaxies of rich clusters. 3C 465-like objects can be considered the extreme low-luminosity end of active nuclei in the centers of rich clusters; the estimated magnitude of 3C 465's nuclear component, at -15.7, is consistent with the precipitous drop of the luminosities of quasars in clusters. 3C 465 appears to represent a new class of optically active objects. 48 refs.
