我们提供了与 2011 年 3 月 8 日在活动区 NOAA 11165 发生的 M4.4 耀斑相关的日珥喷发、日冕环扩张和日冕物质抛射 (CME) 的详细三维 (3D) 视图。耀斑监测望远镜 (FMT) 在搬迁到秘鲁伊卡大学后成功获得了耀斑和灯丝抛射的全盘 Hα 图像。 Hα 线周围的多波长观测使我们能够推导出 Hα 日珥喷发的 3D 速度场。太阳动态观测站上的大气成像仪组件和日地关系观测站 - Ahead 卫星上的极紫外成像仪也获得了极紫外特征。我们发现，在爆发的细丝与日冕磁场碰撞之后，一些日冕环开始扩张，导致清晰的日冕物质抛射的增长。我们还讨论了由膨胀环和周围日冕磁场之间的多重相互作用驱动的日冕物质抛射的后续活动。
We present a detailed three-dimensional (3D) view of a prominence eruption, coronal loop expansion, and coronal mass ejections (CMEs) associated with an M4.4 flare that occurred on 2011 March 8 in the active region NOAA 11165. Full-disk Hα images of the flare and filament ejection were successfully obtained by the Flare Monitoring Telescope (FMT) following its relocation to Ica University, Peru. Multiwavelength observation around the Hα line enabled us to derive the 3D velocity field of the Hα prominence eruption. Features in extreme ultraviolet were also obtained by the Atmospheric Imager Assembly onboard the Solar Dynamic Observatory and the Extreme Ultraviolet Imager on board the Solar Terrestrial Relations Observatory - Ahead satellite. We found that, following collision of the erupted filament with the coronal magnetic field, some coronal loops began to expand, leading to the growth of a clear CME. We also discuss the succeeding activities of CME driven by multiple interactions between the expanding loops and the surrounding coronal magnetic field.
