And the timing couldn't have been more perfect.
I saw the Northern Lights from the plane. The sky turned green for Patrick 💚— Candice (@candysomething) March 17, 2015
The phenomenon occurs when explosions caused by a coronal mass ejection (CME) on the Sun cast magnetically charged particles into space. Most of these particles are deflected by the Earth's magnetic field but as it is weaker at the poles, some of those particles then collide with gas in the atmosphere causing the light display in those area.
Last night, the Aurora was visible much further south across the UK, Scandinavia, Russia and parts of the US. This was a result of a particularly strong CME which left the sun on Sunday.
On social media, Irish people were sharing some gorgeous photos of the event with reports coming in from as far south as Waterford.
Darren Moran also filmed this stunning timelapse video of the sky lighting up over Newport in Mayo which gives an idea of how the Lights move across the sky.
Pretty fitting for the day that was in it.
