Résumé

We present a new diagnostic tool for investigating the plasma conditions in a moving structure in the solar corona, such as an eruptive filament or prominence. It relies on NLTE radiative transfer calculations and the signatures of outward directed velocities on Lyman and Balmer lines profiles. Preliminary observations with SUMER on SOHO are discussed.
