Resumen:
We present a numerical modelling of the interaction between a quiescentfilament and a large-scale shock wavefront passage. Large-scale coronalwaves can perturb distant quiescent filaments, and they might force theireruptions. E.g., after the occurrence of a Moreton event, some observations have reported sudden oscillations -in spatial displacementand intensity- emitted by winking filaments [1,2]. Also, observations haveled to the conclusion that winking filaments are generally coincident withthe wavefront passage of the Moreton coronal counterpart. However,observations have failed to detect the perturbing large-scale wave interaction with the filament at a coronal level; which have generally beenestimated by indirect methods.
