Northern lights illuminate UK skies as far south as England's south coast

The aurora borealis lit up skies across the UK on Friday and Saturday evenings, visible as far south as Devon, Hampshire and Kent.

• The northern lights appeared across the UK on Friday and Saturday evenings, with sightings reaching as far south as Devon, Hampshire and Kent.
• The Met Office said sightings could remain possible during clear skies until Tuesday across Scotland and similar geomagnetic longitudes.
• Geomagnetic activity reached 600nT on Saturday, making the aurora visible across the whole of the UK, a rarer occurrence for southern regions.
• The Met Office said the display occurs when charged particles from solar wind collide with gases in the upper atmosphere, releasing coloured light.
