In recent years, large radio surveys of Active Galactic Nuclei (AGNs),comprising millions of sources, have become available where one couldinvestigate dipole asymmetries, assumedly arising due to a peculiar motion ofthe Solar system. Investigations of such dipoles have yielded in past muchlarger amplitudes than the cosmic microwave background (CMB) dipole, thoughtheir directions seem to lie close to the CMB dipole. Here we investigatedipole asymmetries in two recent large radio surveys, Very Large Array SkySurvey (VLASS) containing 1.9 million sources, covering the sky north of$-40^\circ$ declination, and the Rapid ASKAP Continuum Survey (RACS) containing2.1 million sources, covering the sky south of $+30^\circ$ declination. We finddipoles determined from the VLASS and RACS surveys to be significantly largerthan the CMB dipole. Dipole directions from the VLASS and RACS data differsignificantly from each other. Nevertheless, along with a number of otherpreviously determined dipoles, including the CMB, they all appear to lie in anarrow sky region, which argues for the various dipoles to be related somehow.However, significant differences in their derived peculiar velocities,including that of the CMB, cannot be explained by a peculiar motion of theSolar system, which should necessarily be a single value. Instead, theirdiscordant peculiar velocities may be indicating that different cosmicreference frames are moving relative to each other or that the matterdistribution on cosmic scales is not homogeneous and isotropic, either scenariobeing in contravention of what expected from the Cosmological Principle (CP).
