Afterwards he found a sunspot group which lived the western limb of the sun , to reappear on its eastern limb , and finally to regain its old position .

后来，他发现有一群黑子在太阳西部的边缘上停留了一段时间才消失，然后在太阳东部边缘上。

The characteristic features of the magnetic configuration are the inverted arrangement of the magnetic polarities of the sunspot group , the existence of the 3 magnetic configuration and the violent changes of the magnetic field gradient .

磁场结构的特点是黑子群磁极性排列的倒置、δ磁结构的存在和磁场梯度的剧烈变化。
