Solar Activity Could Cause Minor Geomagnetic Storm on Earth
太陽活動可能導致地球出現輕微地磁風暴
Have you ever wondered what happens when our Sun gets a bit restless?
你是否曾好奇當太陽變得有些躁動時會發生什麼事？
Recently, scientists reported that solar activity could cause a minor geomagnetic storm on Earth.
最近，科學家指出太陽活動可能會在地球上引發輕微的地磁暴。
These events occur when material from the Sun, often in the form of Coronal Mass Ejections (CMEs), travels through space and impacts our planet's magnetosphere.
這些事件發生在來自太陽的物質，通常以日冕物質拋射（CMEs）的形式，穿越太空並撞擊地球磁層時。
When they arrive, they can shake up Earth's magnetic shield.
當它們抵達時，可能會撼動地球的磁場防護罩。
Don't worry, though; this is classified as a G1 storm, which is the lowest level on NOAA's space weather scale.
不過別擔心，這被歸類為 G1 風暴，是美國國家海洋暨大氣總署（NOAA）太空天氣量表中的最低等級。
G1 storms are quite routine and happen frequently during the 11-year solar cycle.
G1 風暴相當例行，在 11 年的太陽週期中頻繁發生。
These minor storms typically cause only tiny fluctuations in power grids or slight drag on satellites.
這些輕微的風暴通常只會導致電網出現微小的波動或對衛星造成輕微的阻力。
The most exciting result is often a beautiful light display known as the aurora, which might become visible at higher latitudes.
最令人興奮的結果往往是稱為極光的絕美光影展演，這在高緯度地區或許清晰可見。
