Abstract
An augmented sample of globular clusters associated with Virgo galaxies is used in a new determination of 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 & Smith and Harris & Petrie. The newly 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 ± 0.3 mag. The present value of the Hubble constant is 80 ± 11 km s–1 Mpc–1.Keywords
