Irish sun-worshippers can catch some spectacular rays in the heart of the capital - by viewing one of the biggest spots ever seen on the sun.
Astronomers in Dublin have been gathering to watch explosions the size of the Earth in the sky through powerful telescopes fitted with special sun filters.
The explosions are occurring around a giant dark spot which appeared on the surface of the sun at the end of last week.
The giant sunspot which is 65,000 miles long can be viewed from Ireland but is expected to disappear in a few days.
The chairman of Astronomy Ireland, Mr David Moore, said there is major explosive activity around the sunspot.
He is expecting hundreds of Irish people to visit their headquarters in Artane in Dublin to view the activity around the dark spot on the sun over the next week.
He said: "We have viewed the sunspot during the week and we were amazed by the extent of the spot and the intricate detail visible all around it. This is very unusual and we're holding free sun shows at our headquarters all week.
"It's the best and most impressive view I've ever seen. It's the kind of thing that happens every decade but I've never seen any spot this big."
He said the dark patch has appeared because a large area of the sun has cooled down. "It's a storm on the sun and it's caused by material from below being blocked from getting to the surface. It's quite similar to a volcano on the surface of the sun. "If you could get close you would see huge bubbles of material coming up from below. The bubbles would be the size of Europe," Mr Moore said.
But he warned sun lovers not to look at the sun without special filters. "People should never look at sun with the naked eye. If they use binoculars or telescopes they can blind themselves before they have time to blink. Within a fraction of a second the sun can burn a mark onto the back of your eye that can't be removed. There are special filters in Astronomy Ireland."
