| 摘要 | Filament eruptions often result in flares and coronal mass ejections (CMEs). Most studies attribute the filament eruptions to their instabilities or magnetic reconnection. In this study, we report a unique observation of a filament eruption whose initiation process has not been reported before. This large-scale filament, with a length of about 360 Mm crossing an active region, is forced to erupt by two small-scale erupting filaments pushing out from below. This process of multifilament eruption results in an M6.4 flare in the active region NOAA 13229 on 25 February 2023. The whole process can be divided into three stages: the eruptions of two active-region filaments, F1 and F2; the interactions between the erupting F1, F2, and the large-scale filament F3; and the eruption of F3. Though this multifilament eruption occurs near the northwest limb of the solar disk, it produces a strong halo CME that causes a significant geomagnetic disturbance. Our observations present a new filament eruption mechanism in which the initial kinetic energy of the eruption is obtained from and transported to by other erupting structures. This event provides us a unique insight into the dynamics of multifilament eruptions and their corresponding effects on the interplanetary space. |
