We determined the kinematics at the jet of 0716+714 from a reanalysis of multi-frequency VLBI data ( 5 , 8.4 , 15 , 22 GHz ) obtained during the last 10 years combined with data from the literature .
For this intra-day variable blazar , only a lower limit of its distance is known ( z \geq 0.3 ) .
We find that 0716+714 is a relatively fast superluminal source ( with a Lorentz factor of \gamma > 15 ) , revising earlier results showing much slower motions .
We discuss the new findings with emphasis on the interpretation of the observed rapid radio variability .
