Ireland is due to witness its most spectacular lunar eclipse for the next 14 years on Monday, 21 January, and astronomy experts are advising those with an interest in it should "take a day off work or school" to catch the event. 

A total lunar eclipse will take place on Monday morning, and with clear skies predicted, it might be the only time Irish people can see one as clear for another 14 years.

A total lunar eclipse happens when the earth comes between the sun and the moon, covering the moon with its shadow. This turns the moon a bright red, so lunar eclipses are often called blood moons. These occur between two and three times every three years.

While they're not the rarest of space events, the weather conditions for Monday's lunar eclipse means it will be particularly noteworthy. As well as this, the moon will be slightly closer to the earth at this point, making it a supermoon. 

It will also be notable for the duration of the eclipse. Astronomy Ireland says that the total part of the eclipse runs for 62 minutes from 4:41am to 5:43am on Monday morning, when the Moon will be high in the West as seen from all of Ireland.

"There will be other total lunar eclipses between 2019 and 2032 but they will happen as the Moon sets or rises from Ireland thus spoiling the view," said editor of Astronomy Ireland magazine, David Moore, as quoted by The Independent.

It's because of this that astronomy experts are recommending that people take days off work or school, or at least get up early on Monday, to catch the spectacular sight.

"Irish people will not see an eclipse this good again until October 2032 so we want everyone to stay up late, or get up early and witness one of the most spectacular sights in nature," Moore said.

If you're a few minutes early or late to the show, so to speak, fear not: there will be two partial eclipses that take place before and after the total eclipse, due to the moon slipping out of the earth's shadow. 

This partial phase will happen both before totality, from 3:34am to 4:41am, and after totality from 5:43am to 6:51am on Monday morning.
