An empirical calibration is presented for the absolute luminosity of type I supernovae using the most reliable distance estimates available to host galaxies of observed supernovae in the Virgo Cluster. Several estimates are presented for the absolute magnitude at maximum blue light; the best one, using planetary nebula distances, gives MB = -18.5 + or - 0.2, and the others give slightly different values consistent with the errors. When combined with published Hubble diagrams for distant supernovae, this calibration leads to a Hubble constant in the range H(0) = 75-100 km/s/Mpc. 41 refs.
