The motion of a spiral wave in an excitable medium due to interaction with a boundary is considered. The drift of the core and the frequency shift, evaluated analytically as a response to a small perturbation of the boundary, are found to be superexponentially weak. It is shown that for some range of parameters the spiral is unstable to small displacements away from the center of a circular domain.
