周六英国部分地区可能会看到北极光

准备好迎接令人毛骨悚然的展示! 从苏格兰可以看到北极光, Northern Ireland and Northern England this Halloween following a ‘significant’ solar flare towards our planet

  • Sightings of aurora are likely in parts of the UK cloud permittingMet Office says
  • Those based-placed are in Scotland, Northern Ireland and the North of England
  • When the charged particles from the sun strike atoms and molecules in Earth’s atmosphere, they excite those atoms, causing them to light up
  • Solar activity could mean the Northern Lights will be seen from the UK on Saturday evening and even into Sunday to accompany Halloween, 专家说.

    The Sun emitted a ‘significantsolar flare – a powerful burst of radiation – on Thursday, 十月 28, 根据 美国宇航局.

    现在, 的 气象局 says the flare and an accompanying coronal mass ejection (芝商所) – a massive expulsion of plasma from the Sun’s corona (its outermost layer) – will be responsible for Saturday evening’s display.

    The Northern Lights are created by disturbances in Earth’s magnetosphere caused by these events, usually concentrated around the Earth’s magnetic poles.

    The Northern Lights – also known as the aurora borealis – is predominantly seen in high-latitude regions (around the Arctic and Antarctic), so any glimpse in the UK is a rare treat for stargazers.

    太阳耀斑和 CME

    太阳耀斑是太阳上的一次巨大爆炸,当储存在“扭曲”中的能量发生时就会发生’ 磁场 (通常在太阳黑子上方) 突然被释放.

    在短短几分钟内,它们将材料加热到数百万度,并产生跨越电磁波谱的辐射爆发, 包括从无线电波到 X 射线和伽马射线.

    太阳耀斑不同于“日冕物质抛射”’ (CME), 曾经被认为是由太阳耀斑引发的.

    CME 是巨大的气泡,带有磁场线,在几个小时内从太阳中喷出.

    ‘Geomagnetic activity is expected to be quiet until Saturday afternoon [十月 30],’ the Met Office says on its website. ‘Any aurora until then is unlikely.

    ‘A significant Earth-directed CME is expected to arrive at Earth later on the 30th lasting into Sunday 31st, with an enhanced auroral oval highly likely.

    ‘Sightings of aurora seem likely along the northern horizon (cloud permitting) across Scotland, Northern Ireland and Northern England.

    ‘There is a slight chance of aurora visible as far south as North Wales, Midlands and Norfolk if looking at the extreme northern horizon low down.

    太阳耀斑与 CME 不同, 曾经被认为是由太阳耀斑引发的. 两者都是太阳风暴的类型.

    美国宇航局解释: “我们通常通过光子看到太阳耀斑 (或光) 它释放, 至多光谱的每个波长.

    “我们监测耀斑的主要方式是在 X 射线和光学光中. 耀斑也是粒子出现的场所 (电子, 质子, 和更重的粒子) 被加速.

    “耀斑是我们太阳系最大的爆炸性事件. 它们被视为太阳上的明亮区域,可持续数分钟到数小时。’








    在地球的北方, the Northern Lights is officially known as the aurora borealis and in the south it is called the aurora australis.

    In the Southern Hemisphere, ‘enhanced auroral oval [是] highly likelyover Antarctica, the Met Office adds.

    ‘There is a slight chance of sightings in the extreme southern horizon (cloud permitting) for New Zealand, South Chile/Argentina and Tazmania,’ 它说.

    几个世纪以来,北极光一直让地球人着迷, 但它背后的科学并不总是被理解.

    地球有一个看不见的力场, 磁层, 保护我们免受来自太阳的危险带电粒子的伤害.

    磁层是地球周围受地球磁场控制的区域.

    科学专家马蒂乔普森解释说: '虽然它庇护我们, 它还创造了地球上最令人印象深刻的现象之一——北极光。’

    “当致命的太阳风遇到地球的磁层时, 一些带电粒子被捕获, 并被沿着地球的磁力线直接推向两极.

    “当他们到达地球时, 它们撞击我们大气中的原子和分子, 以光的形式释放能量。’

    The problem is disruption to our magnetic field creates solar storms that can affect satellites in orbit, 导航系统, 地面电网以及数据和通信网络.

    “有害的太空天气以前曾影响过地球, 但随着我们越来越依赖容易受到太阳爆发影响的系统和技术, 未来的太阳能影响可能更具破坏性,’ 欧洲航天局说 (这个).








    什么是极光以及是什么触发了令人惊叹的自然展示?

    北极光和南极光是在我们的大气层中触发的自然光奇观,也被称为“极光”.

    有两种类型的极光 – 北极光, 意思是“北方的黎明”, 和澳大利亚极光, ‘南方的黎明。’

    通常颗粒, 有时被称为太阳风暴, 被地球磁场偏转.

    但是在更强的风暴中,它们会进入大气层并与气体粒子发生碰撞, 包括氢气和氦气.

    这些碰撞会发光. 尽管浅绿色和粉红色很常见,但极光显示有多种颜色.
