Abstract
OBSERVATIONS made over the past six years show that the rotation measure of the Vela pulsar has increased by 14%, while over the same period the dispersion measure has shown a marginally significant decrease of about 0.2%. These results imply that a region containing a relatively strong magnetic field has moved across the path to the pulsar. This region of strong field is most probably associated with filamentary structure in the Vela supernova remnant.
