Ireland will experience a rare solar eclipse tomorrow morning.

The partial solar eclipse will be visible from around 10am, with people in the southeast likely to have the best chance to witness it.

The event will see almost half the sun blocked out by the moon for around two-and-a-half hours

It is the deepest partial eclipse since March 2015 and Astronomy Ireland has said the country will not see anything deeper until March 2025.

David Moore from Astronomy Ireland said it will be spectacular.

“We want everyone to watch what is a relatively deep, partial eclipse of the sun,” he said.

“It is what is called annular – from the north, it goes over the North Pole, from Canada across to Russia – but from Ireland we will get to see up to 45% of the sun’s diameter covered by the moon.

“It will probably cool down a few degrees – maybe, even if it is a lovely clear blue sky, the day won’t look as bright as it normally does because a third of the sunlight will be gone.”

He said the event will begin at 10am and will be at its peak shortly after 11am.

People in the north of the country can expect to see up to 45% of the sun disappear while other places may experience around 40%.

It is set to be mostly cloudy tomorrow across the western half of the country, with sunny breaks elsewhere.

It will be drier further east with sunshine breaking through at times – offering an opportunity to catch a glimpse of the phenomenon.

As ever, people are being urged not to look directly at the sun while the partial eclipse is happening.

Seanie Morris, from the Midlands Astronomy Club, has this advice:

“Don’t use sunglasses to look directly at the sun or tonight use a telescope or binoculars even with what you think is proper shielding,” he said.

“You will get more enjoyment by taking something like a colander or a sieve or something that has holes in it and use that to project the crescent shapes through those holes onto a background sheet of paper or the pavement on the ground.”

You can also punch a hole in a piece of card to project the image onto a surface you can safely look at.

Ireland's last total solar eclipse was nearly 300 years ago and the next one is not due until September 2090.
