We present three high resolution radio images of the Crab nebula , taken in 1998.6 , 1998.8 and 2000.1 with the VLA .
These are the best radio images of the Crab to date .
We show that , near the pulsar , there are significant changes between our three observing epochs .
These changes have an elliptical geometry very similar to that of the optical wisps .
One radio wisp in particular can be unambiguously identified between two of our observing epochs , and moves outward with an apparent velocity of \sim 0.24 c .
The similarity in both morphology and behavior of the present radio wisps to the optical wisps suggests that they are associated .
This implies that the radio wisps , like the optical ones , are likely manifestations of the shock in the Crab pulsar ’ s wind .
This suggests that the radio emitting electrons are accelerated in the same region as the ones responsible for the optical to X-ray emission , contrary to most current models .
