One of the previously proposed mechanisms for the formation of magnetic ropes in the Venus ionosphere -breakup of the ionopause as a result of the development of the Kelvin-Helmholtz instability - is analyzed. Because the plasma flow in the transitional region is axisymmetric disturbances greater than 50 km in size (characteristic size of the magnetic ropes near the ionopause) are stable for zenith angles 0 less than or equal to 10/sup 0/. It was found that existing data, obtained on the American Pioneer-Venus space probe, also apparently indicate that the ionopause is stable for low dynamic solar-wind pressure.
