  We report results on the QSO 3C345 obtained from VLBA observations carried
out on epochs 1995.84, 1996.41, and 1996.81, at 22, 15, 8.4 and 5 GHz. Total
and polarized images VLBI images were obtained. We observed superluminal
motions of components C8 and C7 with respect to the core component D. We imaged
also the remarkably complex polarization structure near the core.
