波蘭上空的紅色極光
Red Aurora over Poland

北極光通常不會到達如此遙遠的南方。 然而,太陽巨大的活動區 3664 中的磁場混亂產生了表面爆炸,將電子、質子和更大質量的帶電原子核送入太陽系。幾天後,日冕物質拋射(CME)撞擊了地球,並引發了極光,據報道,這些極光離我們星球的南北兩極異常遙遠。 這場免費的天空秀可能還沒有結束--太陽黑子豐富的 AR 3664 已經噴射出更多的日冕物質拋射,這些拋射可能也會在今晚或明天撞擊地球。不過,那個活躍區域現在已經接近太陽邊緣,很快就會旋轉著遠離地球。 圖為昨晚早些時候在波蘭拉西博爾茲拍攝到的一次 6 秒鐘曝光的紅色射線極光。 攝影師的朋友是第一次看到極光,他在遠處也拍攝到了美麗多彩的夜空。 圖片庫:來自太陽活動區域 6443 的全球極光
原文:Northern lights don't usually reach this far south. Magnetic chaos in the Sun's huge Active Region 3664, however, produced a surface explosion that sent a burst of electrons, protons, and more massive, charged nuclei into the Solar System. A few days later, that coronal mass ejection (CME) impacted the Earth and triggered auroras that are being reported unusually far from our planet's north and south poles. The free sky show might not be over -- the sunspot rich AR3664 has ejected even more CMEs that might also impact the Earth tonight or tomorrow. That active region is now near the Sun's edge, though, and will soon be rotating away from the Earth. Pictured, a red and rayed aurora was captured in a single 6-second exposure from Racibórz, Poland early last night. The photographer's friend, seeing an aurora for the first time, is visible in the distance also taking images of the beautifully colorful nighttime sky.
