Puschell, J. J. Abstract A very large-amplitude change in the visual wavelength flux from the radio galaxy 3C 382 occurred on a time scale of about a month during mid-1977. The infrared flux was constant during the onset of the outburst, but showed an increase at 2.28 microns about a year later. Such activity strongly suggests that the observed infrared radiation does not originate in the same component as the visual wavelength radiation. Extension of the spectral-flux distribution to 10 microns shows a flattening between 2.20 and 10 microns. A plausible origin for the infrared flux longward of 2.20 microns is thermal reradiation by hot dust.
