Abstract
VLBI observations of the quasar 3C179 reveal that its two milli arc second components have an apparent relative velocity of 7.6 times the velocity of light. This is the fifth radio source in which ‘superluminal’ motion has been reported but the first which also exhibits double lobe structure on the arc second scale. Statistical arguments which apply to such sources cause difficulties for explanations based on motion in a relativistic jet.
