Query: Motion toward the Great Attractor from an ether-drift experiment   Since the end of 80's, the region of sky of galactic coordinates (l\sim
309^o, b\sim 18^o), corresponding to a declination \gamma\sim -44^o and right
ascension \alpha\sim 202^o, usually denoted as the "Great Attractor", is known
to control the overall galaxy flow in our local Universe. In this sense, this
direction might represent a natural candidate to characterize a hypothetical
Earth's "absolute motion". Our analysis of the extensive ether-drift
observations recently reported by an experimental group in Berlin provides
values of \alpha and \gamma that coincide almost exactly with those of the
Great Attractor and not with the values \gamma\sim -6^o and \alpha\sim 168^o
obtained from a dipole fit to the anisotropy of the CMB. This supports in a new
fashion the existence of a discrepancy between the observed motion of the Local
Group and the direction obtained from the CMB dipole.
