Scientific paper

Large-scale galactic motions suggest that a 'Great Attractor', a large mass of 5.4 x 10 to the 16th solar masses, is centered on galactic longitude l = 307 deg and latitude b = 9 deg at a distance of 4350 + or - 350 km/s. The existence of a very rich concentration of galaxy clusters in this direction which may have a considerable dynamical influence is demonstrated here. The estimated redshift distances of these clusters range from 3000 to 20,000 km/s, with a main complex at roughly 14,000 km/s. The baryocenter of this concentration lies about 25 deg away from the cosmic microwave background dipole and about 10 deg away from the latest reported position of the Great Attractor.
