  Our local motion with respect to the cosmic frame of rest is believed to be
dominantly responsible for the observed dipole anisotropy in the Cosmic
Microwave Background Radiation (CMBR). We study the effect of this motion on
the sky distribution of gravitational wave (GW) sources. We determine the
resulting dipole anisotropy in GW source number counts, mass weighted number
counts, which we refer to as mass intensity, and mean mass per source. The mass
M dependence of the number density n(M) distribution of BBH is taken directly
from the data. We also test the anisotropy in the observable mean mass per
source along the direction of the CMB dipole. The current data sample is
relatively small and consistent with isotropy. The number of sources required
for this test is likely to become available in the near future.
