停電威脅因為太陽風暴襲地球
Power cuts threat as sun storm hits earth

A huge mass of electrically-charged particles thrown out by a gigantic eruption on the Sun is due to strike the Earth tonight.
一個巨大質量的電荷粒子堆被太陽的巨大爆發拋出,到期於今晚襲地球。
Scientists expect it to trigger one of the most violent geomagnetic storms ever recorded.
科學家預期它會引發有記錄以來最猛烈的地磁暴。
The result could be widespread power surges and even blackouts, disrupted TV and mobile phone signals, and broken down communication satellites.
結果可能是廣泛的電源浪湧及甚至停電、干擾電視和手電信號、並且通信衛星死火。
At the same time the Northern Lights, normally confined to polar latitudes, may produce dazzling displays in the skies above southern Britain.
同時,通常僅限於極地緯度地區的北極光,可能會在英國南部天空上面產生耀眼的展示。
At least one satellite has already been knocked out of action by the storm. Japan's space agency said its Kodama communications satellite had been temporarily shut down after malfunctioning.
至少有一顆衛星已被風暴淘汰不能行動,日本航天機構說它的兒玉通信衛星,在故障後已被暫時關閉。
The solar flare that caused the eruption burst out of a sunspot at 10.54am yesterday.
引起爆發的太陽耀斑,在昨天上午10時 54分出自一顆黑子的爆炸。
Experts said it was the strongest flare seen in the past 30 years. The explosion caused a coronal mass ejection (CME) which is now speeding towards Earth.
專家說,這是過去30年所見最強的耀斑,爆炸引起日冕物質的拋射(CME),那在目前向著地球加速。


干擾
Disruption
Last week another CME only hit the Earth a glancing blow, yet was able to disrupt airline communications.
上週另一次 CME只給打地球帶來側擊,但能擾亂航空通信。

The solar flare was classified as an X18-category explosion, meaning it can trigger planet-wide radio blackouts and long-lasting radiation storms.
Although the charged particles present no direct danger to people on the ground, they could have a devastating effect on electrical equipment.
Geomagnetic storms are classified on a scale of one to five. Initial indications are that the looming storm could reach the highest G5 level and last for 24 hours.
Northern Lights
The most obvious manifestation of the storm is likely to be glorious auroras lighting up the night sky.
Usually the Northern Lights, or aurora borealis, is only visible in Britain from northern Scotland. The Earth's magnetic field channels the solar particles that cause auroras towards the poles.
But experts say that over the next two days the Northern Lights may be seen at latitudes as low as Florida and Texas - and even south enough to cover the whole of Europe.
