Scientific paper

VLBI observations of the QSO 4C49.22 show a jet in P.A. 208 deg + or - 3 deg, in the same direction as the innermost structure seen with the VLA. It is concluded that the kpc scale structure seen with the VLA is most likely due to a large-scale hydromagnetic instability in the jet. The lack of sub-kpc curvature suggests that the jet in this source has a smaller proper velocity gamma-beta (although it may still be relativistic), and a greater inclination to the line of sight, than in other extragalactic sources dominated by a compact core. A one-sided jet, which alternately flips 180 deg, is suggested by the observations.
