If you looked into the sky last night you may well have been greeted by a stunning array of colours. One of the strongest geomagnetic storms for years meant that the Northern Lights could be seen across parts of the uk, as our correspondent Louisa Pilbeam reports. Technicolor skies not seen in parts of the uk for more than 20 years. This the scene injersey, as a Spectacular Solar Show was sent from the sun. As far south as padstow, in cornwall, a dazzling display shone another light on our world. Look at the colours overnight in Saffron Walden in essex, and this burst of colour in hertfordshire and in london late last night. Who you the Northern Lights are rare enough. Further north, in crosby beach, in liverpool, people gathered to watch. This was the forth bridge in scotland. The colours are caused by solar storms on the surface of the sun. The story started 93 million miles away and two days ago. What happened was the Magnetic Fields on the sun rearranged themselves, releasing a lot of energy and ejecting billions of tonnes of charged particles out from the sun. And, in europe, these shades dancing across the skies of southern germany. This was manchester, the city bathed in a bright glow, and stunning Aurora Activity above hornsey, in yorkshire, as rays fell, too, on basingstoke, in hampshire. I think we might be in with a chance again tonight. It might not be quite as spectacular as last night but its probably worth trying and, because of the way the geometry works, were always most likely to see it at around midnight. So if you can stay up till midnight and get yourself into a dark place, that would be the thing to do. And, if you do, you may be treated to a rare gift from our universe. Louisa pilbeam, bbc news. Im joined by my colleague tomasz schafernaker, from bbc weather, who was lucky enough to see the Aurora Borealis in london last night. Enough to see the Aurora Borealis just described those magical pictures for eyes. I just described those magical pictures for eyes. Just described those magical pictures for eyes. I tell you what.

Many| it was a dream come true. Many people dream is to see the Northern Lights but in the big city, at home, from your own garden, from the park, it was fantastic and about 10 30pm i started to see a green tint in the sky and bill knew it was going to happen but you never really quite believe it and then i went to the park. I got my very important the eyes used to the dark sky and we saw that spectacular display and, do you know what the amazing thing about this aurora was . It is just so special. Normally, we do get auroras in the south of the uk occasionally. 0f In The South of the uk occasionally. Of course they are better further north but, in the south, folks tend to see just a bit of a tent low on the horizon and that is the best we get whereas i had the aurora right above my head. You get whereas i had the aurora right above my head above my head. You can literally lick it. Above my head. You can literally lick it we above my head. You can literally lick it.

It is definitely going be had to catch it tonight . It 3 definitely going to happen be had to catch it tonight . It 1 definitely going to happen tonight for sure. Greatest chance is always a little bit further north across the uk but almost anywhere is likely. If you look at that graphic, the red colours is pretty much 90100 and the red colours is pretty much 90 100 and then slightly less of a chance in the south but i think if you are out there, you get your eyes used to the diet, you should just about catch it.

What is happening is the sun is has a really complicated Magnetic Field and that Magnetic Field come inside the sun, over 11 years, with colic the sun, over 11 years, with colic the cycle. We are by approaching the peak of this solar cycle which will happen in the next year or so. So the sun is making massive bubbles of gas in our general direction and we were lucky enough last night for that magnetic bubble to hit the earth. It squeezes particles into the earths atmosphere and when those particles, like electrons, collide with the gases inside our atmosphere, it makes this guy glows to the different colours you can see, myself, we were lucky here with the University Of Sussex in that we are surrounded by the countryside so it was a good night to observe the night sky. Last night i could see greens and reds and purples and the green colours, are caused by oxygen. The red colour is caused by nitrogen in our purple colours are caused by hydrogen and helium so those vibrant colours we can see last night are all caused by the different chemicals in our atmosphere. We can actuall , chemicals in our atmosphere. We can actually. Our chemicals in our atmosphere. We can actually, our viewers chemicals in our atmosphere.

We tend to see from the uk, we can see the aurora maybe once or twice every solar cycle, once or twice every 11 years and last solar cycle 11 years ago is back in 2013, i could see some aurora but they were very faint and low on the horizon. Last night was something completely different and i saw the news reports of being able to see the order and expecting something just a little hint of Something Like that so initially i did not care about but then i got a text message from a couple older students from the University Of Sussex and they sent me messages ijust go outside with your camera, it had let the entire sky.

The charity, help for heroes, says many veterans living with chronic pain are not receiving the compensation they deserve from the uk government. Its calling on the Ministry Of Defence to recognise the condition in its own right and to expand Financial Support for those affected. Ministers say theyre continually reviewing policies, and owe a debt of gratitude to all veterans, as john maguire reports. Vicki ross lives her life in constant pain. Always active and fiercely competitive, she plays wheelchair rugby, which you may be amazed to hear helps her to deal with the pain. Its a distraction, but not a cure. Is that ever a time where youre not in pain . Er, i dont think so, other than when im on the operating table. So, yeah, everything hurts at some point. Especially in my knees and my feet and kind of in my shoulder as well. Butjust depending on what i do through the day, so whether im sitting down too much or whether i stand too much or whether i walk you know, that increases the pain and increases the time to recover back to that kind of baseline of pain. She had a very successful military career, but was medically discharged after 22 years. The army had followed playing football for manchester city. A lifetime of sport and physical endurance has taken its toll and despite the scars, she says chronic pain affects her life in so many ways. The kind of Mental Health impact it has, you know, itjust makes everything a lot more difficult, so it makes socialising difficult, it makes work difficult, and then, you know, you start to doubt yourself. Even when you have this pain, it changes your life, it changes the person you once were. You know, that has its own kind of Mental Health impact. Shes backing the campaign by help for heroes, a charity for the armed forces, to have chronic pain diagnosed as a medical condition in its own right. Its one of those, i guess, disabilities that you cant see, and people just dont understand. So it has a huge impact on your life notjust your life, if you look wider, yourfamily, yourjob, how you are as a member of society. It can be crippling for some people. Having achieved so much in her personal, professional, and sporting life, vickis determined to continue being as active as she possibly can. And when chronic pain is doing its utmost to defeat her, that determination is this former soldiers most valuable weapon. John maguire, bbc news, staffordshire. The Taliban In Afghanistan say more than 300 people are now known to have died in devastating flash floods in the north of the country. A spokesman for the Interior Ministry told the bbc that most of the casualties were in the province of baghlan. Emergency teams have been sent to rescue those stranded by the floodwaters. On friday, a massive torrent of water swept away hundreds of houses in several villages. Dozens of people are still missing. With me is our reporter sofia bettiza who has been following the story. This sounds like a desperate situation. What more can you tell us . That is right. Desperate and devastating few hours for thousands of people in afghanistan put up essentially, what happened is that the northern part of the country has been hit by unusually heavy rainfall and that has caused the flooding that we are looking at. Now, the bbc has been sent several videos and images from some people in the country and those show the scale of the damage and in those images we can see violent torrents of water sweeping through houses. People trapped in their own homes trying to get to safety by climbing on top of their rooftops but also people who are believed to be trapped under the mud and under the rubble. Now, as you said, the un is saying that more than 300 people are believed to have died and we also understand that more than 2000 houses have been destroyed. Bud more than 2000 houses have been destro ed. � ,. , destroyed. And we continue to report on Natural Disasters destroyed. And we continue to report on Natural Disasters in destroyed. And we continue to report on Natural Disasters in afghanistan i on Natural Disasters in afghanistan with these earthquakes and floods like this. How common is flooding in particular, there have been conversations about whether this is linked to Climate Change . Conversations about whether this is linked to Climate Change . There are several factors linked to Climate Change . There are several factors that linked to Climate Change . There are several factors that cause linked to Climate Change . There are several factors that cause flooding l several factors that cause flooding but Climate Change is definitely a key reason why this is happening at the moment. And this is because of the moment. And this is because of the fact that it is getting hotter, it is causing more extreme rainfall but also, interestingly, according to experts, is one of the countries in the world most at risk because of Climate Change. It has been a particularly dry winter and that makes it very hard for their soil to absorb such a huge amount of water but also, afghanistan is one of the poorest countries in the world, ravaged by decades of war. When these things happen, you know, the country is not exactly well equipped to deal with Natural Disasters. In terms of what happens next, we know more than 300 people are known to have died but there are still many who are missing and so the fear at the moment is that the death toll could rise significantly. The moment is that the death toll could rise significantly. Thank you for bringing could rise significantly. Thank you for bringing us could rise significantly.
