The northern lights illuminated skies across the UK on Friday and Saturday evening, treating sky-gazers as far south as Devon, Hampshire and Kent to the dazzling natural phenomenon.
The Met Office said sightings could continue in clear skies until Tuesday, with further displays possible across Scotland and similar geomagnetic longitudes.
The aurora borealis is a natural light display in Earth's sky, driven by solar activity and geomagnetic storms interacting with the upper atmosphere. Such occurrences are mostly visible near the Arctic Circle and northern Scotland.
Displays occur when charged particles collide with gases in the atmosphere around the magnetic poles. As they collide, light is emitted at various wavelengths, creating colourful displays.
According to the Met Office, the sun emits charged particles known as solar wind, which travel at about a million miles per hour. Video footage captured from space by a Russian cosmonaut showed the spectacular aurora from orbit.
