A relation between the eruptivity of an active region and the existence of filaments seen in the same rotation and/or the previous ones - up to five rotations ahead - is pointed out. This statistical study was based on the 'Cartes Synoptiques de la Chromosphere Solaire et catalogues', prepared at Meudon Observatory, and concerns 3300 Active Regions observed between 1974 and 1980. It is shown that the previous filaments (phantoms) influence the level of the eruptivity mainly in the growing and maximum phases of the cycle. When only the seats of more than 10 flares are taken into account, the relation between the location of these flares and the filaments becomes more accurate and more independent of the phase of the cycle (latitude) than is the case for the general eruptivity. This relationship may be interpreted as a signature of a long-lived magnetic perturbation impressed into the solar atmosphere even after the birth of the active region and the disappearance of the filaments. As the latitude does not influence this relation, these seats are related to an anomalous behavior of the differential rotation of the region, able to explain the energy storage for flares.
