现在，近代历史上最大的太阳黑子群之一正在穿越太阳。3664活动区不仅很大，而且很猛烈，向太阳系抛射粒子云。其中一些日冕物质抛射已经在影响地球，其他的可能也会随之而来。在极端情况下，这些太阳风暴可能会导致一些地球轨道卫星故障，地球大气层轻微扭曲，电网激增。当这些粒子撞击地球上层大气时，可以产生美丽的极光，据报道，一些极光已经出现在异常遥远的南方。图中AR3664和它的黑子是昨天在意大利罗马的可见光下拍摄的。AR3664太阳黑子群是如此之大，以至于只有用专为上个月日全食设计的眼镜才能看到它。这个周末，天文爱好者们将会热切地观看全球夜空中明亮而不寻常的极光。图集：3664活动区上的太阳和相关的极光

Right now, one of the largest sunspot groups in recent history is crossing the Sun. Active Region 3664 is not only big -- it's violent, throwing off clouds of particles into the Solar System. Some of these CMEs are already impacting the Earth, and others might follow. At the extreme, these solar storms could cause some Earth-orbiting satellites to malfunction, the Earth's atmosphere to slightly distort, and electrical power grids to surge. When impacting Earth's upper atmosphere, these particles can produce beautiful auroras, with some auroras already being reported unusually far south. Pictured here, AR3664 and its dark sunspots were captured yesterday in visible light from Rome, Italy. The AR3664 sunspot group is so large that it is visible just with glasses designed to view last month's total solar eclipse. This weekend, skygazing enthusiasts will be keenly watching the night skies all over the globe for bright and unusual auroras. Gallery: Active Region 3664 on the Sun and Associated Aurora
