Observations of flux density and very-long-baseline interferometric measurements of the rapidly variable radio source 3C 120 are shown to support a model first proposed by Ozernoy and Sazonov. This model suggests that explosions of supernova magnitude occur approximately every 1.2 years at the center of the galaxy, ejecting two similar synchrotron-radiating plasmoids at moderately relativistic velocities in opposite directions making a large angle with the line of sight. As the plasmoids move outward they also expand at a rate comparable to the ejection velocity.
