| Abstract: | The diagramV - log(1 +z
e
) as function of ( ,  ) is considered for the quasars. HereV is the apparent visual magnitude,z
e
is the emission line redshift, and are the equatorial coordinates. Two opposite extreme  spots NE and SE are observed on the sky, where the inclination of the straight line fitting the dependenceV - log(1 +z
e
) is maximum and minimum. The coordinates of the centres of these extreme spots are (
NE,
NE) = (282°, +42°) and (
SE,
SE) = (70°, -38°) with errors 5°. A hypothesis of the Superattractor (SA) is proposed to explain such an effect. Two independent tests of this hypothesis are realized. First, the dependence or the frequency a of the absorbers in QSO spectra on (, ) is investigated. A region of the larger a is found. The coordinates of its centre are (, ) = (82°, - 10°) with error 5°. Second, the cases ofz
