Wales was treated to a spectacular northern lights display on Sunday night and forecasters are saying that there could be another chance to catch them on Monday. A Met Office spokesman said the rare sightings of the aurora borealis further south in the UK on Sunday night were due to the "strength" of a geomagnetic storm and the "strip of cloudless skies" in southern regions.
Royal Museums Greenwich explained on its website that the lights are caused by solar storms on the surface of the sun giving out clouds of electrically-charged particles which can travel millions of miles and collide with the Earth. Most particles are deflected away but some are captured in the Earth's magnetic field and accelerate down towards the north and south poles, colliding with atoms and molecules in the Earth's atmosphere, according to the observatory.
They can be seen from time in the UK but to see them as far south as Pembrokeshire is very unusual. Take a look at the pictures from Wales here.
