A huge complex filament was observed between 28 December 2000 and 7 January 2001. We have analyzed its dynamics and its sudden disappearance. We analyze the 3-D coronal magnetic field extrapolated from MDI photospheric magnetograms and compare with filament coronal images. The filament erupted in a CME after a mild helical up-awarded movement of plasma on 7 January. We attempt to explain this CME event onset by kink instabilities. An approach to estimate the filament helicity and magnetic flux injection explain the filament destabilization.
