在太阳的边缘，创造了最近的极光的巨大活动区域是什么样子的？在那里，AR 3664更好地展示了它的3D结构。照片中，从混乱的太阳黑子区AR 3664向太空中延伸出一个巨大的多管状日珥，这只是从这个剧烈的太阳区域喷射出的粒子云的一个例子。地球可以很容易地适应这个长期延伸的日珥。这张特色图片是两天前在这个不断变化的地区拍摄的。昨天，多年来最强的太阳耀斑被驱逐（未显示），爆炸被归类为上x级。来自耀斑的紫外线迅速击中地球大气层，导致北美和南美的短波无线电中断。尽管ar3664的粒子现在稍微远离地球，但来自ar3664的粒子和随后的日冕物质抛射（cme）可能仍然会沿着弯曲的磁场线穿过太阳系内部，并产生更多的地球极光。画廊：来自太阳活动区3664的地球极光

What did the monster active region that created the recent auroras look like when at the Sun's edge? There, AR 3664 better showed its 3D structure. Pictured, a large multi-pronged solar prominence was captured extending from chaotic sunspot region AR 3664 out into space, just one example of the particle clouds ejected from this violent solar region. The Earth could easily fit under this long-extended prominence. The featured image was captured two days ago from this constantly changing region. Yesterday, the strongest solar flare in years was expelled (not shown), a blast classified in the upper X-class. Ultraviolet light from that flare quickly hit the Earth's atmosphere and caused shortwave radio blackouts across both North and South America. Although now rotated to be facing slightly away from the Earth, particles from AR 3664 and subsequent coronal mass ejections (CMEs) might still follow curved magnetic field lines across the inner Solar System and create more Earthly auroras.
