The Supernova Cosmology Project has discovered over twenty-eight supernovae(SNe) at 0.35 = 0.2, wefind that H_0^G < 70 km/s/Mpc in a Lambda=0 universe and H_0^G < 78 km/s/Mpc ina flat universe, correcting the distant and local SN apparent magnitudes forlight curve width. Lower results for H_0^G are obtained if the magnitudes arenot width corrected.
