它比地球还大。它是如此之大，你甚至可以在太阳表面看到它，而不需要放大。它拥有强大而纠结的磁场以及众多的黑子。它被称为AR 3664，它发展成为近年来在太阳上看到的最具活力的区域之一，释放出一系列的爆炸，导致大量高能粒子撞击地球，创造了美丽的极光。而且可能会继续下去。尽管像AR 3664这样的太阳活跃区域可能相当危险，但该区域的日冕物质抛射还没有对地球轨道卫星或地球表面电网造成太大损害。这是几天前在意大利罗马奇维塔韦基亚拍摄到的巨大的活跃区。这张合成图像只对太阳表面进行了很短的曝光，但模拟了实际可见的情况。最后，AR 3664现在正在远离地球旋转，尽管该区域可能存在足够长的时间来再次旋转。画廊：来自太阳活动区3664的地球极光

It was larger than the Earth. It was so big you could actually see it on the Sun's surface without magnification. It contained powerful and tangled magnetic fields as well as numerous dark sunspots. Labelled AR 3664, it developed into one of the most energetic areas seen on the Sun in recent years, unleashing a series of explosions that led to a surge of energetic particles striking the Earth, which created beautiful auroras. And might continue. Although active regions on the Sun like AR 3664 can be quite dangerous, this region's Coronal Mass Ejections have not done, as yet, much damage to Earth-orbiting satellites or Earth-surface electrical grids. Pictured, the enormous active region was captured on the setting Sun a few days ago from Civitavecchia, Rome, Italy. The composite image includes a very short exposure taken of just the Sun's surface, but mimics what was actually visible. Finally, AR 3664 is now rotating away from the Earth, although the region may survive long enough to come around again. Gallery: Earth Aurora from Solar Active Region 3664
