Abstract: Let $ M$ be a hyperbolic Riemann surface of finite volume. The harmonic dual form to an infinite geodesic joining two punctures on $ M$ is obtained in two different ways. First of all, using the degeneration of hyperbolic Eisenstein series, it is made explicit in terms of these. Secondly, generalizing the construction of Kudla and Millson to the case of an infinite geodesic joining two punctures, we give an automorphic realization of this harmonic form.
