People in the southeast of the country look set to have the best opportunity to witness a rare solar event tomorrow morning.
A Partial Solar Eclipse, where almost half of the Sun's diameter is covered, will occur, and will be the deepest partial eclipse since 20 March 2015.
According to Astronomy Ireland, there will not be a deeper partial solar eclipse from Ireland until 29 March 2025.
Editor of Astronomy Ireland magazine David Moore said that although Ireland is a long way from the centre line of the Annular Eclipse, if skies are clear tomorrow, people should get a chance to see "this extremely rare natural spectacle".
Eclipses happen once or twice every year around the world, but are often only visible in very inaccessible remote places.
"The good news for Ireland is that the eclipse will be high in the sky, about 50 degrees up in the southeast," said Mr Moore.
He said the eclipse will begin just before 10am, with the "first bite" being taken out of the Sun, and it should end just before 12.30pm.
The maximum eclipse will occur a few minutes after 11am where people in Donegal may see up to 45% of the Sun’s diameter being covered, while people in other places around Ireland will see at least 40% of the Sun covered.
Ireland's last Total Solar Eclipse was in 1724, with the next one not due until 23 September 2090.
If you are planning to check the skies tomorrow morning, remember you must never look directly at the sun, either with the naked eye or with devices such as telescopes or binoculars, as it can severely damage your eyes.
There are some safe ways to view the eclipse, however, including CE approved special eclipse viewers, which have filters on them that protect the eyes from the harmful effects of the Sun.
A simple pinhole projector, made with a piece of card or stiff paper, will also work.
Punch a hole in the card and hold this in front of a second piece of paper and the image of the Sun will be projected through the hole onto the second piece of paper, keeping your eyes safe.
Alternatively, there will be many viewing events, including one by Astronomy Ireland, which plans to livestream the eclipse.
Researchers at I-LOFAR in Birr Castle Demesne, Co Offaly and DIAS Dunsink Observatory in Dublin will have solar telescopes with cameras set up at both locations and will be also be live streaming the event.
Met Éireann is forecasting a warm and humid day tomorrow, with cloudy conditions in the western half of the country.
