The temperature dependence of the ac susceptibility of sintered YBCO pellets is experimentally analysed in detail few Kelvin below the transition temperature. The quite complex dependence of X' and ~" on the frequency and the amplitude of the ac magnetic field cannot be explained by an ohmic Flux Fl
