We'll have the chance to see part of a solar eclipse just before 8 o'clock on Monday evening.
The moon is due to cover almost half of the sun over Ireland, with those in the west and northwest having the best chance of seeing the partial eclipse.
Astronomy Ireland says at 7.55pm on Monday, the moon will start passing in front of the sun causing a partial eclipse that will be visible from all of Ireland.
A full eclipse will be seen in the US, Canada and Mexico.
Editor and Founder of Astronomy Ireland Magazine, David Moore, says it's been 400 years since Ireland has witnessed a total solar eclipse.
A total eclipse will be visible seen across a thin strip from Mexico, USA to Eastern Canada.
"It will not be a total eclipse of the sun from Ireland as these are extremely rare with the last one being visible from Irish soil in 1724, exactly 400 years ago this year."
Head of Education and Outreach at MTU’s Blackrock Castle Observatory in Cork, Frances McCarthy, says those in the west and northwest will have the best view.
"From Cork, we're only going to get 20 percent of the sun covered up by the moon. So, go west if you can. The further west you are, the better it will be. Belmullet will get nearly 40% coverage.
"If you're in the west and north you're going to see a little bit more.
"I'm sorry for the people on the east coast. You're looking at the smallest sliver of the moon covering up, and a little bit of the sun will be extinguished".
