The Pink Moon will rise in the skies above North Wales tomorrow.
The astronomical phenomenon is the second full moon of April but despite its name, the Pink Moon will actually be a different colour.
So what exactly is the Pink Moon? And where does the name come from?
Here's everything you need to know about April's defining full moon.
What is the Pink Moon?
The Pink Moon, which is the second full moon of April, happens once a year.
This astrological event occurs when the moon is located exactly on the opposite side of the Earth from the sun.
This means its face is fully illuminated, resulting in a full moon.
When is it?
The Pink Moon will be making its appearance tomorrow morning (April 19).
Its full moon phase is expected to occur at around 12 midday, so keep an eye out from late morning.
According to space.com , the moon will be three days past perigee - which is the the point in its orbit where its satellite is nearest to Earth.
This means it'll appear larger and brighter than usual, with experts referring to it as "almost" a supermoon.
But don't be disappointed if you were hoping to witness an official supermoon - there's two more expected later this year .
Why is it called the Pink Moon?
"Every month's full moon has a nickname that can often be traced back centuries to the Native Americans or early colonials from Europe," revealed Acuweather .
It added that the Pink Moon of April is believed to originate from its appearance of a 'moss pink' or the wild ground phlox - one of the first flowers of spring.
And despite its nickname, the full moon doesn't often even appear pink - instead sometimes visible as yellow, orange or even red.
The colour ultimately depends on the atmospheric conditions right as it first peers over the horizon.
