摘要：

Distances from the Tully-Fisher relation have been measured with the Parkes radio telescope for eight additional southern clusters of galaxies in the redshift range 2500-5000 km s-1. Most of them have large (average 1000 km s-1) positive peculiar velocities in a comoving frame in which the microwave background radiation shows no dipole anisotropy. In five out of eight cases these measurements have a significance at or above the 2 sigma-level. Outflow is seen on both sides of the Galactic plane. The source of this large-scale flow, if gravitational in origin, lies at or beyond the limit of our sample.
