We analyzed the space distribution of 117 galaxies in an area of 0.9 deg radius centered on NGC 6045 in the Hercules cluster in the velocity range 9000 to 14,000 km/s. By taking advantage of 74 morphologies based on CCD images, we succeed in isolating a cluster of galaxies with an average velocity of 11,467 km/s located to the NE of the assumed centroid of A2151, where early and late type galaxies share the same dynamical properties. The implications of this result for the nature and identification of the x-ray source is briefly discussed.
