The stability of a traveling roll system, which results from the development of a primary instability of the flow between a stationary and a rotating disk, is experimentally studied. The characteristics of this traveling pattern and of the bifurcation from which it results are obtained. We show in particular that the band of the stable roll modes is limited by the Eckhaus secondary instability.
