10.7 GHz VLBI observations of the giant double-lobed quasar 4C 34.47 (1721 + 343) are presented. Previous VLBI monitoring at 5 GHz indicated the presence of superluminal motion in the core of this large radio source, at velocities of about 2.5/h c (Barthel et al., 1989). In the present observations, the superluminal nature of the apparent motions is confirmed. The evolution of the individual core components is studied in greater detail.
