  The divergence of the momentum density field of the large scale structure
generates a secondary anisotropy contribution to the Cosmic Microwave
Background (CMB). While the effect is best described as a non-linear extension
to the well-known integrated Sachs-Wolfe effect, due to mathematical
coincidences, the anisotropy contribution is also described as the lensing of
the dipole seen in the rest-frame of a moving mass. Given the closeness, there
is a remote possibility that local concentrations of mass in the form of the
Great Attractor and the Shapley concentration generate large angular scale
fluctuations in CMB and could potentially be responsible, at least partly, for
some of the low-multipole anomalies in WMAP data. While the local anisotropy
contribution peaks at low multipoles, for reasonable models of the mass and
velocity distributions associated with local super structures we find that the
amplitude of temperature anisotropies is at most at a level of 10$^{-2}$ $\mu$K
and is substantially smaller than primordial fluctuations. It is extremely
unlikely that the momentum density of local mass concentrations is responsible
for any of the large angular scale anomalies in WMAP data.
