The absolute magnitude Mpg brightness decline rate β relation Mpg = -20m.41+0.17(β-10) is derived on the basis of supernovae in the Local Supercluster. For the Local Group infall velocity and the global value of the Hubble constant the estimates ΔV = 144±103 km/s and H0 = 45±7 km/s/Mpc are obtained.
