In a quasi 1‐dimensional lateral gas‐discharge system we observe experimentally sub‐ and supercritical bifurcations from a spatially homogeneous to an inhomogeneous distribution of the current density. Among other results we find for the first time the simultaneous existence of a nontrivial nonstationary pattern (travelling waves) with a nontrivial stationary pattern (periodic filaments) in a laterally extended dc‐driven gas‐discharge system.
