A novel localized structure of traveling waves (TWs) was observed at convection onset in ethanol-water mixtures. It is one of various possible flow patterns of TWs which were observed. We find that for almost-one-dimensional cell geometry unique dynamics of transient behavior (in the form of two counterpropagating TWs) can lead to various stable states.
