active solar region

基本解释

Just as a sunspot was turning away from Earth on Sept. 8, the active region erupted, producing a solar flare and a fantastic prominence.
9月8日正当太阳黑子开始远离地球的时候，活跃区域又发生一次爆发，同时出现一个明显的突起。
The main characteristics of the perturbations can be explained by the variations of the ionizing sources which were located in the solar active region.
利用当时太阳活动区离化源的变化可以解释扰动的主要特征。
Spicules line the above frame of solar active region 11092 that crossed the Sun last month, but are particularly evident converging on the sunspot on the lower left.
这些针状体在上个月穿过太阳的太阳活跃区域 11092 号中形成一条条线，不过聚集在左下角太阳黑子上的针状体特别的明显。
