Abstract

VLBI observations of 3C147 reveal that its core is a low-frequency variable radio source which has brightened by a factor of 2 in 6 years. In combination with X-ray observations, this implies that bulk relativistic motion is taking place within the core, and leads to the prediction that 3C147 is a member of the class of superluminal radio sources.
