The superluminal quasar 3C 345 has a curved, one-sided jet-like radio structure. Ejected material has been observed travelling at apparent speeds of 13 - 17 c. The authors report new observations at 22 GHz which show that the most recently ejected component is not moving radially away from the compact radio core, but along a trajectory which could be interpreted as either a curved path originating in the compact core, or a straight line, in which case the origin of ejection is not coincident with the compact radio core. The observations provide evidence of acceleration of this component.
