Astronomy Ireland is to hold eclipse watches in the Phoenix Park, Dublin, and around the State this evening, when a rare total eclipse of the moon is to take place.
No telescope or other equipment is needed to appreciate the spectacle, which will lead the moon to appear a coppery colour for over an hour.
It is thought this will be the best such eclipse to be visible from Ireland until 2029, with the moon becoming one million times dimmer.
The moon will first enter the earth's shadow at 9.30pm tonight and will be "totally eclipsed" from 10:44pm to 11.58pm, before fully leaving the Earth's shadow at 1.12am tomorrow.
"A darkened chunk will appear on the moon's edge, growing as time progresses to eventually swallow the entire disc . . . when it will appear a coppery red colour," Astronomy Ireland said in a statement.
"Don't let clouds put you off - this event is so long that any clouds will almost certainly break if you check every few minutes.
"We've seen eclipses on rainy nights in the past, so persevere whatever the weather."
The locations for eclipse watches include Ballyphehane community centre, Cork, the Papal Cross car park, Phoenix Park, Dublin, the Millennium Statue, Blackrock, Co Louth, and Kilmhil, Co Clare.
