Forecasters say there might be another chance to catch the northern lights on Monday night. There was a spectacular display on Sunday night into Monday morning with people from the Shetland Islands to the Isle of Scilly where skies were clear.
There were reports of sightings of the lights in Cardigan, Pembrokeshire, the Gower and the Brecon Beacons following a huge geomagnetic storm registering 4 out of 5 on the scale. The northern lights are most active during the Equinox and Solstice in March/April and September/October.
And BBC Weather say there could be another change to see them again on Monday night, but there is a warning that temperatures are set to drop if you are planning to head out. They say: "There might be another chance to catch the aurora tonight. Be prepared for a chilly one though. As skies clear in many areas, the temperatures will drop quickly."
The Met Office forecast for Wales tonight could be good news for stargazers.
It says: "Rain clearing during the evening with some showers for a time. Clearer skies developing overnight with light winds allowing for a frost to develop. Minimum temperature 0 °C."
Normally, on the rare occasions they are seen in the UK, only Scotland and parts of northern England and Northern Ireland are treated to glimpses of the electrically-charged particles from space entering the Earth's upper atmosphere at high speed. But they have been seen several times in Wales this year already.
Photographer Dan Santillo, who took a stunning picture in the Gower, said: "Last night, a dream came true - I saw and captured the Aurora Borealis (aka northern lights) over Rhossili Bay."
