这个巨大的橙色球要滚下绿树成荫的小山了吗？不，因为这个巨大的橙色球实际上是太阳。12天前，我们太阳系的中心恒星被拍到从地球上的一座小山上升起，它的前景非常详细，令人愉快。太阳的圆盘显示了五个太阳黑子，考虑到在过去几年太阳活动的太阳极小期，大多数日子没有黑子，这是相当多的。近距离观察这座山——西班牙彼得的锡德山——不仅能看到松树的剪影，还能看到人的剪影——巧合的是，摄影师的三个兄弟。在拍摄这张精心策划的照片时，这些树和兄弟在大约3.5公里外。黑暗的滤光片淡化了通常明亮的太阳，使较低的太阳黑子更加清晰。几分钟之内，太阳就从山上升起，而在一周之内，太阳黑子围绕太阳旋转，消失在人们的视线之外。然而，捕捉到的场景现在被定格在时间里，供所有人欣赏。

Is this giant orange ball about to roll down that tree-lined hill? No, because the giant orange ball is actually the Sun. Our Solar System's central star was captured rising beyond a hill on Earth twelve days ago complete with a delightfully detailed foreground. The Sun's disk showed five sunspots, quite a lot considering that during the solar minimum in solar activity of the past few years, most days showed no spots. A close look at the hill -- Sierra del Cid in Perter, Spain -- reveals not only silhouetted pine trees, but silhouetted people -- by coincidence three brothers of the photographer. The trees and brothers were about 3.5-kilometers away during the morning of the well-planned image. A dark filter muted the usually brilliant Sun and brought up great detail on the lower sunspots. Within a few minutes, the Sun rose far above the hill, while within a week, the sunspots rotated around the Sun, out of view. The captured scene, however, is now frozen in time for all to enjoy.
