Abstract An analysis of the Pioneer Venus Orbiter plasma and magnetic field observations suggests the existence of a large-amplitude rotational wave in the Venusian ionosheath. This wave appears to be the standing superalfvenic wing. It is located within the shocked plasma flow outside the boundary of the tail. The rotation of the magnetic field by about 90° across the wave is accompanied by the vector change of plasma velocity with the magnitude of the plasma velocity jump quite close to the value of a vector jump of the Alfven velocity.
