No back-side infall into the Great Attractor

This Letter presents the first results of a survey of the peculiar velocities of 1355 spiral galaxies in the southern sky using the Tully- Fisher relation to estimate their distances. The most important result of these measurements is that no back-side infall into the Great Attractor is found, contrary to the findings of Dressler & Faber; rather, evidence is found for a bulk flow of about 600 km s^-1^ on scales greater than 60 h^-1^ Mpc. This, when added to the bulk flow of 450 km s^-1^ recently found by Willick in the opposite part of the sky, suggests that there is bulk flow in the supergalactic plane over very large scales greater than 130 h^-1^ Mpc. The origin of this bulk flow is a puzzle.
