Abstract : Flux density and very long baseline interferometric measurements of 3C120 at several wavelengths and times have been analyzed in terms of a model proposed by Ozernoy and Sazonov (1969). Highly satisfactory agreement is achieved if explosive outbursts, each releasing a few times 10 to the 51st power erg, have occurred approximately every 1.2 years since 1967.0. Each outburst ejects a pair of radio plasmoids in opposite directions at moderately relativistic velocities. The individual components expand, also relativistically, as they travel outward. The rate of component expansion is just sufficient to ensure that inverse Compton losses are negligible. (Author)
