We have measured the Hubble constant H _ { 0 } in NGC 564 at cz \approx 5800 km s ^ { -1 } and in NGC 7619 at cz \approx 3700 km s ^ { -1 } with deep I–band Surface Brightness Fluctuation distance measurements at the ESO Very Large Telescope ( VLT ) .
We obtain H _ { 0 } = 70 \pm 7 \pm 6 km s ^ { -1 } /Mpc for NGC 564 and H _ { 0 } = 68 \pm 6 \pm 6 for NGC 7619 .
The actual SBF sample used for the measurement of H _ { 0 } in the Hubble Space Telescope Key Project on the Extragalactic Distance Scale ( Freedman et al .
2001 ) amounts to six galaxies .
When we combine the measurements from this work with our previous VLT I–band SBF distance measurement in IC 4296 ( Mei et al .
2000 ) , we obtain : H _ { 0 } = 68 \pm 5 \pm 6 km s ^ { -1 } /Mpc .
When we add the Freedman et al .
( 2001 ) SBF sample , we obtain H _ { 0 } = 71 \pm 4 \pm 6 km s ^ { -1 } /Mpc .
