Scientific paper

The variations in intensity and velocity inside an eruptive filament, observed on May 30, 2003 with CDS and EIT on-board SOHO, are analysed in the transition region He I line and the coronal Mg X line. Vertical oscillating motions of the filament with damped velocity oscillations before its disappearance are revealed. The link between theses oscillations, the flaring regions nearby and the filament eruption is investigated.
