The J/$\\psi$ is detected via its dimuon decay in the forward rapidity region ($-4.0 < y < -2.5$) for events where the hadronic activity is required to be minimal. The analysis is based on an event sample corresponding to an integrated luminosity of about 750 $\\mu$b$^{-1}$. The cross section for coherent J/$\\psi$ production is presented in six rapidity bins.
