Abstract

Galaxy distances and velocities are needed to determine the expansion rate of the Universe, as described by the Hubble constant H(sub 0). Accurate distances of nearby galaxies and clusters are needed to measure indirect distance indicators, using Cepheid variable stars. A Cepheid distance of 18.6 plus or minus 1.9 (statistical error) plus or minus 1.9 Mpc (systematic error) for the galaxy NGC1365 in Fornax is reported.
