Scientific paper

A Doppler image of the silicon distribution on the magnetic Ap star CUVir is presented. This distribution is characterized by a large circular spot of relative silicon depletion (with respect to the mean value across the star) that is coincident with the positive magnetic pole. An elongated spot of enhanced silicon is centred at the expected location of the negative magnetic pole. If silicon is enhanced where the magnetic field is horizontal, as is predicted by diffusion theory, then this distribution is consistent with a magnetic dipole whose axis is decentred by about 0.2 in stellar radius along the dipole axis.
