摘要

The rotation of eruptive filaments is not only related to the kink instability occurring in the solar corona but also may result from the interaction between the large-scale magnetic field and the eruptions themselves. This interaction could likewise make the filament deflect in the radial direction. By means of data obtained by the Atmospheric Imaging Assembly on board the Solar Dynamics Observatory and observations from the Solar Terrestrial Relations Observatory, we study an eruptive filament showing both rotation and non-radial motion. The consequence of the three-dimensional reconstruction of the filament axis indicates that a significant rotation was simultaneous with the severe deflection in the latitude during the eruption. In combination with the results of a derived coronal magnetic configuration, our observations suggested that the non-radial motion resulted from the interaction between the eruption and an overlying pseudostreamer. Moreover, we find that the deflection of the eruption is asymmetric, with its eastern segment being dragged more significantly than its western one. Therefore, we suggested that the action of the asymmetric deflection is possibly an alternative mechanism for the rotation of the eruptive filament.
