We report complex impedance measurements in an untwinned YBaCuO crystal. Ourbroad frequency range covers both the quasi static response and the resistiveresponse of the vortex lattice. It allow us to characterize the irreversibilityline without the need of any frequency dependent pinning parameters. We confirmthe validity of the two modes model of vortex dynamic, and extract both thesurface critical current and the flux flow resistivity around the first ordertransition $T_{m}$. This latter is identified by the abrupt loss of pinning andby an unexpected step of $\rho_{ff}(T)$ at $T_{m}$.Comment: accepted for publication in EPJ
