The Northern Lights put on spectacular show for parts of the UK and Ireland overnight.
The Aurora was seen across large parts of Ireland, Scotland, northern England and Wales.
It is caused when solar particles are thrown out into space and collide with the Earth's magnetic field.
Forecasters say the current positions of the Earth and Sun may give us a number chances to glimpse the lights over the next few weeks.
As well as the time of year, a "coronal hole" near the Sun's equator had aligned with the Earth and was sending a burst of high-speed solar winds to strike the planet.
