一个异常活跃的太阳黑子区域正在穿越太阳。这个区域被标记为ar4366，比地球大得多，在过去的十天里产生了几次强大的太阳耀斑。在这张特色图片中，该区域在太阳圆盘的右上方以大而暗的太阳黑子为标志。这张照片是5天前在墨西哥萨卡特卡斯的一座小山上拍摄的。AR 4366已经成为整个11年太阳周期中最活跃的太阳区域。太阳活动区通常与地球上极光活动的增加有关。现在到达边缘，AR 4366将在下周开始远离地球。然而，目前还不知道，活跃区域是否能存活足够长的时间，在大约两周的时间里，随着太阳的旋转，重新出现。

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.
