現在,近期歷史上最大的太陽黑子群之一正在穿越太陽。活動區 3664 不僅大,而且很猛烈,向太陽系丟擲粒子云。其中一些CMEs 已經在撞擊地球,其他CMEs 也可能隨之而來。 在極端情況下,這些太陽風暴可能會導致一些地球軌道衛星出現故障,地球大氣層輕微扭曲,電網驟增。當這些粒子撞擊地球高層大氣時,會產生美麗的極光,據報道,一些極光已經出現在異常遙遠的南方。 圖為昨天從義大利羅馬用可見光拍攝到的 AR 3664 及其黑子。AR 3664 太陽黑子群非常大,只需戴上為觀看上月日全食而設計的眼鏡就能看到。 本週末,觀天愛好者們將在全球各地的夜空中仔細觀察明亮而不尋常的極光。 相簿:太陽上的 6443 活動區
原文: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 6443 on the Sun
