Sunspots

An absence of sunspots also means an absence of solar flares and their more violent siblings, coronal mass ejections.

黑子的缺失还预示着太阳耀斑的缺席，同时，猛烈的日冕喷发也不会出现。

When sunspots release their electrical energy, they shoot beams of negatively charged electrons into space, some of which escape into the earth's atmosphere.

当太阳黑子释放其电能时，它们带有负电荷的电子束射入太空，其中有一部进入地球的大气层。

In this paper, The mean of a month, mean of a year for the number of sunspots are worked out by the observations of sunspot from 1986 to 1995 in Beijing Planetarium, and we also study and analyze the solar activity of the 22-nd Cycle.

就北京天文馆天文台1986～1995年内的太阳黑子观测资料进行整理，得到黑子数的月均值、年均值，并对本周太阳活动性作了分析研究。

This is the reason for the lack of sunspots during this solar cycle.

这就是为什么在这个太阳周期里会缺乏太阳黑子的活动。

在馆内小天文台借助折射望远镜能观察太阳黑子、月球环形山、木星大红斑、土星光环等有趣的星体现象。

The11-year solar cycle, which governs the appearance of sunspots, also changes the sun's magnetic field.

太阳黑子的出现周期是每11年一次，这个周期性活动同时改变太阳的磁场。
