The Northern Lights are set to make a return above Donegal and many other parts of the country tonight.
Just a few weeks ago Donegal skywatchers were treated to one of the greatest displays of the Aurora in living memory.
Thousands of people caught magical images on their phones while many saw the spectacular dancing lights with their own eyes.
Scientists say tonight could be another such occasion.
Despite a lot of cloud over Donegal and the rest of the county at present, it is expected the skies will clear meaning thousands could see the natural phenomenon appear again.
Due to a geometric storm, the Northern Lights could be dancing across Donegal again tonight.
