In this study we consider numerically the natural frequencies of a free liquid interface in a partly filled right circular cylinder at microgravity conditions. The dependence on the static contact angle, the fill height ratio and the boundary condition at the contact line was investigated. A formula for the calculation of the natural frequency is provided.
