我们首次详细观测了三次连续的、相互依赖的暗条喷发，这三次喷发在5小时内从单个活动区范围以外的不同位置逐一发生。第一次喷发是从活动区观测到的，与日冕物质抛射(CME)有关，在CME期间形成了弥漫的复杂的日冕暗淡，主要延伸到位于安静太阳区域的另外两个暗条。然后，两个静止的细丝连续经历了第二次和第三次喷发，而附近的暗淡是持续的。对比日冕磁组态的结果，暗区之间的磁连通性表明，它们是由第一次喷发所强迫的上覆环系的简单扩张以及其喷发场与周围磁结构相互作用或重新连接的共同作用造成的。请注意，第一次喷发中的变暗过程表明，覆盖在另外两个灯丝上的磁场约束减弱并部分移除，因此人们可以在物理上将这些喷发联系起来，作为共鸣。在我们的事件中，特殊的磁场构型似乎在很大程度上有利于交感细丝喷发的发生。由于日冕暗淡是太阳喷发中频繁而普遍的现象，特别是在CME事件中，它们很可能代表了一种普遍的因素，可以将附近连续的喷发与交感喷发联系起来。
We present for the first time detailed observations of three successive, interdependent filament eruptions that occurred one by one within 5 hr from different locations beyond the range of a single active region. The first eruption was observed from an active region and was associated with a coronal mass ejection (CME), during which diffuse and complex coronal dimmings formed, largely extending to the two other filaments located in quiet-Sun regions. Then, both quiescent filaments consecutively underwent the second and third eruptions, while the nearby dimmings were persistent. Comparing the result of a derived coronal magnetic configuration, the magnetic connectivity between the dimmings suggested that they were caused by the joint effect of simple expansion of overlying loop systems forced by the first eruption, as well as by its erupting field interacting or reconnecting with the surrounding magnetic structures. Note that the dimming process in the first eruption indicated a weakening and partial removal of an overlying magnetic field constraint on the two other filaments, and thus one can physically connect these eruptions as sympathetic. It appears that the peculiar magnetic field configuration in our event was largely favorable to the occurrence of sympathetic filament eruptions. Because coronal dimmings are frequent and common phenomena in solar eruptions, especially in CME events, it is very likely that they represent a universal agent that can link consecutive eruptions nearby with sympathetic eruptions.
