摘要：

We determined the kinematics at the jet of 0716+714 from a reanalysis of multi-frequency VLBI data (5, 8.4, 15, 22GHz) 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 >= 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.
