Descripción: We study 14 cases of dynamic "disparition brusque" (DBd), the sudden disappearance of quiescent filaments/prominences, during two solar minima: 1985-1986 and 1994. The basic material is the systematic optical observations especially from Paris-Meudon Observatory (PMO). We discuss the association of DBs to the solar corona such as coronal holes (CHs) and Coronal Mass Ejections (CMEs) and consequent solar wind and geomagnetic field disturbances (geomagnetic storms or GMSs). We identified two extreme GMSs correlated to joint event cases composed by dynamic DBs with adjacent CHs without associated CME. Furthermore, the highest geoeffectiveness is observed in association to a largest size (>30°) DBd accompanied by a nearby (<15° distance) equatorial CH, which reduces or disappears until the following Carrington Rotation (CR).
