Eerie snaps caught the second full moon of October - known as the blue moon - as it rose across Europe tonight.
It's the first time a full moon will be visible on Halloween eve across the whole world since 1944.
The first blue moon at Halloween in 76 years enchanted Brits lucky enough to see it.
And it could be at least 19 more years before the event transfixes sky-watchers once more.
David Moore from Astronomy Ireland, said: "The Halloween full moon probably only happens a few times every century and it won't happen again in Ireland and the UK until 2039."
Why is it called a Blue Moon?
Unfortunately, its name has nothing to do with its colour and the moon should just look pearly grey.
Blue moons aren't actually blue - the confusion is because the term originates in "blewe", the old English word for "betrayer".
A blue moon refers to the very rare occasion when a full Moon appears for the second time in the same month.
This year we had a full moon on October 1 called the Harvest Moon.
Nasa previously explained: "According to modern folklore, a blue moon is the second full Moon in a calendar month.A blue moon rises behind a cross above a church tower in the Old City of JerusalemCredit: AFP or licensors The blue moon lights up the night sky as it rises over ruins of the Acropolis of Lindos on the island of Rhodes, GreeceCredit: Athena Picture Agency Tonight's blue moon is seen in Alcala de Henares, Madrid in SpainCredit: EPA A spooky second full moon in a month rises over Ankara, TurkeyCredit: Getty Images - Getty The Moon won't actually be blue in colourCredit: Getty Images - Getty It will also be a Micromoon, meaning it will be a smaller than usual full MoonCredit: Getty Images - Getty
When is the best time to see the Blue Moon?
"Usually months have only one full moon, but occasionally a second one sneaks in.
"Full moons are separated by 29 days, while most months are 30 or 31 days long; so it is possible to fit two full moons in a single month.
"This happens every two and a half years, on average."
Weather permitting you should be able to see it in all its bright glory after nightfall but try to avoid light polluted areas.
It's also being referred to by some as the 'Hunter's mlue moon' because it appears around the time that Native American tribes would gather meat for the winter ahead.
And, as if this Moon didn't have enough names already, it will also be a technically be a Micromoon.
A Micromoon is the opposite of a Supermoon and means that the Moon will look a bit smaller than the average full Moon.
In fact, the Moon will be around 31,000 miles further away tomorrow than it would be during a Supermoon.
