It is known that the spatial distribution of galaxies and quasars is structured at a scale LS = 130 h⁻¹Mpc. The same scale can be present at a spatial distribution of the physical characteristics of quasars. The search of period ≈ LS was conducted in the radiospectral indices of quasars in a centimetre range. The Veron-Cetti & Veron catalogue [10] was used as source. In the power spectra of series of spectral indices and proper distances of quasars the peak corresponding to the expected period confidently emerges. 0.23 ± 0.03 estimation of the parameter of density was obtained by the method of smoothing the period in different ranges of z at the varying parameter of density in the flat model of Universe. Interpretation of argument of periodicity, as proper distance, results in a geocentrism. The conformable time is proportional to proper distance and is also a good approximation of the argument of periodicity when the parameter of density equals to 0.23. At the temporal character of the exposed periodicity the centred position of the observer is not required. In such interpretation the exact expression for the argument of periodicity is unknown. The proper distance or the conformable time is introduced by its true values with an accuracy not worse than 1%.
