On the Large Scale CMB Polarization
  We discuss the large scale polarization of the cosmic microwave background
induced by the anisotropy of the spatial geometry of our universe. Assuming an
eccentricity at decoupling of about $0.64 10^{-2}$, we find an average large
scale polarization $\Delta T_{pol}/ T_0 = (0.5 - 1.0) 10^{-6}$. We suggest that
the fortcoming polarization data at large scales from Planck will be able to
discriminate between our proposal and the generally accepted reionization
scenario.
