In this work we consider the changes of the SZ cluster brightness, flux andnumber counts induced by the motion of the Solar System with respect to theframe defined by the cosmic microwave background (CMB). These changes areconnected with the Doppler effect and aberration and exhibit a strong spectraland spatial dependence. The correction to the SZ cluster brightness and fluxhas an amplitude and spectral dependence, which is similar to the first ordercluster peculiar velocity correction to the thermal SZ effect. Due to thechange in the received cluster CMB flux the motion of the Solar System inducesa dipolar asymmetry in the observed number of clusters above a given fluxlevel. Similar effects were discussed for $\gamma$-ray bursts and radiogalaxies, but here, due to the very peculiar frequency-dependence of thethermal SZ effect, the number of observed clusters in one direction of the skycan be both, decreased or increased depending on the frequency band. Adetection of this asymmetry should be possible using future full sky CMBexperiments with mJy sensitivities.Comment: 7 pages, 6 figures, submitted to Astronomy and Astrophysics,  corrected pdf-proble
