Anisotropic thermal Sunyaev-Zel'dovich effect and the possibility of an
  independent measurement of the CMB dipole, quadrupole and octupole
  We consider the effect of the cosmic microwave background (CMB) frequency
spectral distortions arising due to the Compton scattering of the anisotropic
radiation on Sunyaev-Zel'dovich (SZ) clusters. We derive the correction to the
thermal SZ effect due to the presence of multipoles with $\ell=1,2,3$ in the
anisotropy of the CMB radiation. We show that this effect gives us an
opportunity for an independent evaluation of the CMB dipole, quadrupole and
octupole angular anisotropy in our location using distorted signal from the
nearby galaxy clusters and to distinguish between the Sachs-Wolfe (SW) and the
Integrated Sachs-Wolfe (ISW) effects by combining such signals from distant and
nearby clusters. The future space mission 'Millimetron' will have unprecedented
sensitivity, which will make it possible to observe the spectral distortion we
are considering.
