Also known as aurora borealis, the bands of pink and green light were seen across the UK and in parts of Europe last week after an extreme geomagnetic storm caused them to be more visible, according to the US National Oceanic and Atmospheric Administration. The latest sun storm activity follows a period of flares and mass ejections of coronal plasma that threatened to disrupt power and communications on Earth and in orbit.

Met Office space weather expert Krista Hammond said the sunspot region will be rotated back towards Earth in 10 to 12 days’ time, paving the way for further geomagnetic storms and displays of the Northern Lights. “The sunspot region will be coming back round onto the Earth facing side of the sun,” she said. Aurora displays occur when charged particles collide with gases in the Earth’s atmosphere around the magnetic poles.



The sun is currently in the most active period of its 11-year cycle. Said Ms Hammond: “We’re currently at solar maximum and we’re seeing more sunspots. “If we see more sunspots, we see this increased frequency in space weather and therefore the aurora.

” The forecaster downplayed the chances of a full repeat of last weekend’s display, but said more solar activity would mean a good chance of sightings “in the coming weeks, months and years”. “It was such a unique set of circumstances that happened l.
