Received: 12.VI.2017, Accepted: 21.IX.2017
Abstract. We determine a nondegenerate centroaffine ruled surface such that the image of its center map lies on a plane containing the origin. A centroaffine minimal surface such that the image of the center map lies on a plane not containing the origin is also exhibited.
