Surface magnetohydrodynamic wave propagation on a magnetic interface in a cold plasma is studied. The anisotropic ion viscosity is taken into account. Only long waves damping weakly in a wave period are considered. The dispersion equation is obtained. This equation is shown always to have exactly on
The Alfv6n surface waves can arise due to the discontinuity in the Alfv6n speed across the interface along which these waves propagate. This note studies the relationship between VA~ and VA2 which is required for the existence of Alfv6n surface waves in low-fl plasma.
