Abstract
A test o f the isotropy o f Hubble law on the field o f quasars-Correlation with the local supercluster. Selecting quasars on the ground of intrinsic parameters makes a first test of the isotropy of Hubble law possible. Hemispheric anisotropy of H 0 is not significant and has to be less than-25 %, + 34 %. A correlation with the geometry of the Local Supercluster is discussed.
