Northern Lights could return to UK in ‘once in a decade’ event

A ‘once in a decade’ solar event take place over the next few months – and it means you’ll get even more chances to see the Northern Lights. The neon spaghetti strings of green, red and blue have become an increasingly common occurrence in, of all places, people’s back gardens in London this year.
But the Met Office say that the lights will be visible farther south more frequently next year because of a shift in the sun’s magnetic fields. Every 11 years or so, the sun’s magnetic fields flip over. We’re now approaching the tail end of this process, called the solar maximum when the sun gets especially revved up and spits out all sorts of solar goo at us.
When all this sun gunk, called solar flares, splatters onto the earth, this causes the northern lights. ‘While it’s not possible to know precisely what this means for individual Earth-directed solar events, it does mean there will likely be further chances of aurora visibility in the UK in the coming months,’ says Krista Hammond, of the Met Office Space Weather Operations Centre (MOSWOC).
‘While we’re in the solar maximum phase now, which could last a year, it’s not possible to know exactly when the number of sunspots peaked until some time after it has happened.’. The northern lights, or aurora borealis, are caused when atoms get a little too excited by solar winds smashing into the Earth’s magnetic field.
