An optical discharge has been obtained for the first time in the slow burning regime with a steady-state gas motion pattern. A model is proposed for describing the gas dynamics of the discharge propagation, in which the ratio of the observed velocity to the velocity of the discharge through a gas at rest is equal to the ratio of the sound velocities in the discharge and in the cold gas.
