在太陽的高空中，有一個特別活躍的太陽黑子區域正在移動。這個區域被稱為AR 4366，比地球還要大，過去十天內已經產生了幾次強烈的太陽耀斑。在這幅圖片中，你可以看到這個區域在太陽盤的右上方，有著大而黑的太陽黑子。這張照片是在五天前，從墨西哥的薩卡特卡斯的一個山丘上拍攝的。AR 4366現在被認為是這整個11年太陽週期中最活躍的太陽區域之一。活躍的太陽區域常常會引起地球上極光活動的增加。現在，AR 4366已經到達邊緣，接下來的一周將會慢慢轉向背對地球。不過，目前還不知道這個活躍的區域能否生存到兩周後重新出現，因為太陽會不斷旋轉。
原文:
An unusually active sunspot region is now crossing the Sun. The region, labelled AR 4366, is much larger than the Earth and has produced several powerful solar flares over the past ten days. In the featured image, the region is marked by large and dark sunspots toward the upper right of the Sun’s disk. The image captured the Sun over a hill in Zacatecas, Mexico, 5 days ago. AR 4366 has become a candidate for the most active solar region in this entire 11-year solar cycle. Active solar regions are frequently associated with increased auroral activity on the Earth. Now reaching the edge, AR 4366 will begin facing away from the Earth during the coming week. It is not known, though, if the active region will survive long enough to reappear in about two weeks’ time, as the Sun rotates.
