Abstract

Reviews observational situation in the measurement of peculiar velocities in the local universe. Emphasis is placed on such topics as: Do spirals and ellipticals yield the same peculiar velocity field? What is the cluster velocity distribution function? What is the convergence depth of the local universe, as seen by inspection of motions of clusters and of field galaxies? Are there large-scale bulk flows? A reconstruction of the density field and an estimate of the Hubble constant are also given.
