N2 - I calculate the parity violating asymmetry Apv for elastic electron scattering from Al27 in order to compare with the Qweak experiment "background" Al27 measurement. I find that Coulomb distortions, and the quadrupole form factor, reduce Apv near the diffraction minimum. The Qweak data can be used to confirm the neutron radius of Al27, if nuclear structure uncertainties are indeed small, as I suggest, and one can estimate inelastic and impurity contributions. This could provide an important check of the measurement, analysis, and theory.
