北京多地再現極光奇景,地磁暴“導演”夜空大片?

   時間:2024-10-12 03:24 來源:ITBEAR作者:陸辰風

據央視新聞報道,今天凌晨,受地磁暴的影響,北京多處地點再次觀測到了極光現象。這是自今年5月11日前后以來,我國北緯40°地區第二次能夠觀測到極光。

中國氣象局指出,盡管我國地磁緯度較低,平時較難觀測到明顯的極光,但極光的發生高度可達100公里甚至300至400公里的高空,這一高度足以跨越上千公里的地平線。在合適的條件下,我國極北地區,如新疆、黑龍江的最北端,也有可能觀測到極光。

國家空間天氣監測預警中心此前曾發布預測,從10日晚間至11日晚間,可能會出現大地磁暴。若無新的爆發活動,12日可能會出現小到中等程度的地磁暴,之后逐漸恢復正常。

據透露,自10日晚間開始,特別是11日凌晨至12日凌晨的這段時間,我國北部地區有機會觀測到較為明顯的極光,部分地區甚至可能看到紅綠復合極光。
