在相对较短的时间间隔内发生在不同地点的太阳爆发被认为是同情的。然而，很难确定它们之间是否存在因果关系。在这里，我们研究了2014年12月20日X1.8级耀斑后失败和成功的灯丝喷发，其中滑动式磁重联是喷发之间的关键因果联系。重连的特征和影响被确定为：在经历失败的爆发的暗条两侧，蛇形带沿着色球网络延伸，远离暗条，而一个热环明显地在其上方生长;在经历成功的爆发的暗条处，覆盖的冷环收缩，而日冕变暗甚至在暗条爆发之前就出现在两侧。这些效应是通过重连来理解的，重连不断地将覆盖在一个灯丝上的磁通量转换到另一个灯丝上，这调整了磁场如何随着灯丝上方的高度增加而以相反的趋势衰减，因此加强或削弱了每个灯丝的磁约束。
Solar eruptions occurring at different places within a relatively short time interval are considered to be sympathetic. However, it is difficult to determine whether there exists a cause and effect between them. Here we study a failed and a successful filament eruption following an X1.8-class flare on 2014 December 20, in which slipping-like magnetic reconnections serve as a key causal link among the eruptions. Reconnection signatures and effects are identified as follows: at both sides of the filament experiencing the failed eruption, serpentine ribbons extend along the chromospheric network to move away from the filament, while a hot loop apparently grows above it; at the filament undergoing the successful eruption, overlying cold loops contract, while coronal dimming appears at both sides even before the filament eruption. These effects are understood by reconnections continually transforming magnetic fluxes overlying one filament to the other, which adjusts how the magnetic field decays with increasing height above the filaments in opposite trends, therefore either strengthening or weakening the magnetic confinement of each filament.
