The
UK was treated to a rare glimpse of the Northern Lights after the natural
display lit up skies across the country. One of nature’s true wonders, the
Aurora Borealis could be seen as consisting of spectacular “curtains” of red
and green lights, and was visible as far south as Gloucestershire, Essex and
Norfolk last night (February 28).
But
those in Scotland and northern England got the clearest view, with many taking
to Twitter to share their experiences. Daisymay wrote: ‘You could see the
Aurora Borealis in the Isle of Skye. So damn perdy.’
Richard
Wilson, from Guildford, Surrey, who saw it from the air, added: ‘Great view of
the Northern Lights from 30,000 feet over Scotland tonight. Awesome sight!’
The
Light formations are usually only visible in the more northern parts of the UK
so Alex Green, who works for the National Trust in Norfolk, was surprised when
he saw them further south.

‘Wow,
a life tick! Northern Lights over the north Norfolk Coast and visible with the
naked eye! Just amazing!’ he said.
1. The
Northern Lights are caused by the interaction of the solar wind - a stream of
charged particles escaping the Sun - and our planet's magnetic field and
atmosphere.
2. As
the solar wind approaches, it distorts the Earth's magnetic field and allows
some charged particles from the Sun to enter the Earth's atmosphere at the
magnetic north pole and the magnetic South Pole. Then, as these charged
particles "excite" gases in our atmosphere, they make them glow -
just like gas in a fluorescent tube.
3. The
solar wind can cause the Earth's magnetic field lines to disconnect from our
planet. When these field lines "snap back" into position, charged
particles from the solar wind are again pushed into the Earth's atmosphere,
causing aurora. The more magnetic field lines that disconnect and snap back,
the further south the Northern Lights can be seen.

To
increase the chance of seeing the Aurora Borealis, scientists advise viewers to
sign up to an alert service such as Aurora Watch UK, and head outside at
"magnetic midnight" - between 8pm and 12am in the UK - to find a dark
place with no light pollution.

Superb blog .... I know a few people that have done fairly well for themselves by investing in smaller but more secure companies................ ...... Free Solar Panels
ReplyDeleteIt is really interesting and fun to watch the process............... Free Solar Panels
ReplyDeleteloved it thanks for sharing this. i remember reading about this in out textbooks that its one of the most beautiful phenomena in the world. I also write about space and astronomy if you are interested checkout Astronomers found 20 new moons orbiting Saturn
