An extreme geomagnetic storm was observed early Saturday morning, the most powerful occurring in nearly 20 years, a meteorological expert said.
一位氣象專(zhuān)家表示,周六凌晨觀測(cè)到了一場(chǎng)極端的地磁風(fēng)暴,這是近 20 年來(lái)最強(qiáng)烈的一次。
"China's National Center for Space Weather announced its first watch of a G5 geomagnetic storm — the strongest rating on scale from G1 to G5 — early Saturday morning since 2006," said Chen Anqin, chief forecaster of China's National Center for Space Weather on Saturday.
中國(guó)國(guó)家空間天氣中心首席預(yù)報(bào)員陳安勤周六表示:“周六凌晨,中國(guó)國(guó)家空間天氣中心首次觀測(cè)到了G5地磁暴,這是自2006年以來(lái)G1到G5級(jí)別中最強(qiáng)的一次。”
A G4 storm was observed at 11 pm on Friday (Beijing time), and it then upgraded to G5 and lasted from 5 am through 11 am on Saturday, Chen said.
陳說(shuō),周五晚上11點(diǎn)(北京時(shí)間)觀測(cè)到G4級(jí)風(fēng)暴,然后升級(jí)為G5級(jí)風(fēng)暴,并從周六早上5點(diǎn)持續(xù)到上午11點(diǎn)。
"Since Wednesday, multiple moderate and strong solar flares were associated with coronal mass ejections. This has disturbed the Earth's magnetic field and resulted in this round of geomagnetic storms," she said, adding that there is a high possibility of more G3 storms, G4 storms or even G5 storms in the coming days.
她說(shuō):“自周三以來(lái),多次中度和強(qiáng)烈的太陽(yáng)耀斑與日冕物質(zhì)拋射有關(guān)。這擾亂了地球磁場(chǎng),導(dǎo)致了本輪地磁風(fēng)暴。”她補(bǔ)充說(shuō),很可能會(huì)出現(xiàn)更多的G3、G4風(fēng)暴。 未來(lái)幾天會(huì)有風(fēng)暴,甚至 G5 風(fēng)暴。
Sudden ionospheric disturbances were observed in parts of China in the past 24 hours, the center said.
該中心表示,過(guò)去24小時(shí),中國(guó)部分地區(qū)觀測(cè)到電離層突發(fā)擾動(dòng)。
Some netizens shared online the strong aurora they saw in Altay, situated in the northern part of Northwest China's Xinjiang Uygur autonomous region.
有網(wǎng)友在網(wǎng)上分享了他們?cè)谖挥谥袊?guó)西北部新疆維吾爾自治區(qū)北部的阿勒泰看到的強(qiáng)烈極光。
The center issued a red alert on geomagnetic storm at 9 am on Saturday, the highest in its warning system, predicting more occurrence in the following days and cautioning about the impact of the storms on short-wave communication, navigation systems and in-orbit satellites.
該中心于周六上午9點(diǎn)發(fā)布了地磁風(fēng)暴紅色警報(bào),這是其預(yù)警系統(tǒng)中的最高級(jí)別,預(yù)計(jì)未來(lái)幾天將有更多地磁風(fēng)暴發(fā)生,并警告磁暴對(duì)短波通信、導(dǎo)航系統(tǒng)和在軌衛(wèi)星的影響。
