Abstract

Optical-infrared (0.36-3.5 microns) photometric data of the radio galaxy 3C 382, obtained in 1976, show a distinct excess at the longest wavelengths, an ultraviolet excess, and a significant increase in brightness since previous photometry by Sandage (1972). A flux excess at infrared wavelengths has also been observed from 3C 227. These properties demonstrate the presence of emission not attributable to stars, probably originating in the nucleus, extending into the infrared portion of the spectrum.
