The region surrounding the nucleus of 3C 120 has been recorded on electronographic plates, in U, B, V and Varcmin colours. It has been possible to substract the contributions of the bright nucleus and the galaxy. Faint condensations appear. Their colours show that they are probably not emitting synchrotron radiation. The brightest condensation does not coincide exactly with the knot of the radio jet. It is probably of the same nature as Minkowski's Object: burst of star formation triggered by the collision of the jet with relatively dense extranuclear gas.
