N2 - The stability of the Venus ionopause is examined in light of the importance of gravitation and curvature. Using a one fluid approximation for the equation of motion of the plasma, and ignoring the effects of neutrals, a dispersion relation is obtained that includes the effects of magnetic field, sheared plasma flow, buoyancy, centrifugal force, and magnetic tension due to boundary curvature. Buoyancy is found to act to neutralize the flute instability. As expected, the Kelvin-Helmholtz mode is the dominant instability over most of the dayside ionopause.
