Total eclipses of the sun and the moon are quite rare, but this one will be visible across large parts of the planet.
A blood moon will be visible across Ireland and much of the world next week as a total lunar eclipse is set to take place in the early hours on Monday, 21 January.
The eclipse – also known as a 'blood moon' – will be visible from countries in Europe, Asia, Africa, North America, South America, Pacific, Atlantic, Indian Ocean, and the Arctic.
The blood moon is a rare celestial event in which Earth appears in a straight line between the moon and the sun. The shadow of Earth’s atmosphere filtered through sunlight appears as a red sheen on the surface of the Moon.
This will be the last opportunity to view a partial lunar eclipse from Ireland and the British Isles for three-and-a-half years, until 16 May 2022.
The Moon will be in partial eclipse for just over four hours, however, it will all be occurring in the middle of the night.
Starting from just after 2:30am GMT on Monday morning, the Penumbral Eclipse (the point at which you look up and notice a dark shading on the moon’s face) continues on for just under an hour.
Maximum Eclipse (the stage during which the Moon's disk completely covers the Sun) kicks off at 5:12am GMT and continues for roughly half an hour.
A weather forecast has not yet been issued for Monday 21, but the weekend is set to be cloudy with showery outbreaks of rain, "but also good dry periods with normal temperatures for January", according to Met Éireann.
"Sunday is looking colder with sunshine and blustery showers. A sharp frost is likely on Sunday night," they continued.
A fogless evening would be optimum for viewing on Monday night, for those willing to stay up until 5am to view the rare celestial event.
The circumstances of this eclipse are very nearly perfect for observers in North West Europe.
In addition to Ireland and the UK, the eclipse will be visible in its entirety from the Americas, and in Europe from Portugal and Norway as well as parts of Spain, France, Finland, and Sweden.
Observers in other parts of Europe will see the Moon set before the end of the penumbral phase, though most of the continent will be able to view the event up to the end of totality.
Speaking to Irish Tatler, BBC TV and Weather Presenter Barra Best informed us on how to achieve optimum results when moon-gazing on Monday.
"The total eclipse will be visible from right across Ireland - weather permitting, of course. So there's no need to travel any distance, although getting away from light pollution from towns and cities would probably give you a better view," Best says.
"It's also the last time that a lunar eclipse in its entirety can be seen from Ireland for 10 years - the next is 2029."
