美國天文學家預測今天將有一個太陽風暴侵襲地球,或影響電力供應及衞星運作,在高緯度地區可能出現極光。

美國太空總署(NASA)本周較早前觀察到一次太陽耀斑(solar flare),太陽耀斑釋放的帶電粒子現正向地球方向移動,並將引發太陽風暴。美國國家海洋及大氣管理局(National Oceanic and Atmospheric Administration)估計,風暴會於今天衝擊地球。

A solar storm is forecast to hit Earth early Thursday after the Sun unleashed a powerful solar flare — a burst of high-energy radiation — Sunday night.

NASA's Solar Dynamics Observatory Satellite captured a solar flare on the Sun releasing a coronal mass ejection (CME) around 8:25 p.m. ET Sunday.

"[CMEs] are huge explosions of magnetic field and plasma from the Sun's corona," the Space Weather Prediction Center (SWPC) explained in a post online. "When CMEs impact the Earth's magnetosphere, they are responsible for geomagnetic storms and enhanced aurora."

The National Oceanic and Atmospheric Administration (NOA) issued a G1 (minor) geomagnetic storm watch for Thursday.
