But using Koyama's record, they could precisely follow specific sunspots and clusters through that journey.

但利用小山的记录，在这一过程中，研究人准确跟踪特定的黑子或黑子群。

Solar flares and coronal mass ejections often occur near sunspots.

太阳耀斑和日冕物质抛射经常发生在太阳黑子附近。

What are sunspots and why are they dark?

什么是太阳黑子，为什么它们是黑色的?

The least sunspots in an 11-year period is considered solar minimum, while the most sunspot signifies the solar maximum.

太阳黑子量最少的11年时期被认为是太阳活动极小期，而太阳黑子量最多的时期则代表太阳活动极大期。

Around the edges of sunspots, the magnetic field lines are concentrated.

在太阳黑子的边缘，磁力线是集中的。

The Italian scientist Galileo was among the first astronomers to study sunspots.

意大利科学家伽利略是最早研究太阳黑子的天文学家之一。

This creates a bright rim around sunspots called faculae (Latin for “little torch”).

这就在太阳黑子周围形成了一圈亮边，被称为光斑（拉丁文的意思是“小”）。

The areas of the strongest fields coincide exactly with the position of sunspots.

磁场最强的部位正好就是太阳黑子的位置。

At the beginning of a cycle the jet stream is found, like sunspots, in mid-latitudes.

在一个活动周期开始的时候，就找到高速气流，像中纬度地区的太阳黑子。

Ironically, sunspots actually increase the energy output of the Sun.

具有讽刺意味的是，太阳黑子实际上增加了太阳的能量输出。

What results are relatively dark blemishes on the solar surface called " sunspots" .

结果在太阳表面形成了黑斑，称为“太阳黑子”。

This cycle can be visibly measured by an increase and decrease of sunspots on its surface.

这个周期通过太阳表面黑子的增减来进行明确测量。

" A direct measure of solar activity is the number of sunspots on the surface, " Reinhold said.

" 太阳活动的一个直接测量方法是太阳表面的黑子量，" 莱因霍尔德说。

The second study which suggests something odd is happening looked at the strengths of sunspots.

表明奇怪的事情正在发生的第二项研究检查了太阳黑子的活力。

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

缺少太阳黑子也意味着太阳耀斑及它们更强烈的同胞-日冕物质抛射的不存在。

And the newer one also uses a secret formula based on mathematics, astronomy, sunspots, tides and the Earth's position.

它也使用了秘密公式，基于学、天文学、太阳黑子、潮汐和地球位置。

They also worked out that the latitude of this wind is related to the sunspot cycle.

他们还计算出这次太阳风的纬度和太阳黑子的活动周期相关。

Sunspots are caused by irruptions into its surface of the sun's deeper magnetism.

太阳黑子是由入侵活动进入太阳深层磁性表面造成的。

These flares typically emanate from the vicinity of sunspots and can travel all the way to Earth's atmosphere.

这些耀斑通常在太阳黑子附近爆发，并一路直冲地球大气层。

Sunspots are only dark in relation to the bright material around them.

黑子的暗只不过是对应着周围明亮的物质而言。
