Scientific paper

An augmented sample of globular clusters associated with Virgo galaxies is used in determining the present value of the Hubble constant. The new cluster sample combines the detailed photometry of Hanes and the deeper but photometrically less precise counts of Harris and Smith and Harris and Petrie. An extended luminosity function for the Virgo globular clusters is compared with the function defined by the globular clusters seen in Local Group galaxies to reveal that the apparent distance modulus of the Virgo cluster is 30.7 + or - 0.3 mag. The present value of the Hubble constant is 80 + or - 11 km/s/Mpc.
