Skygazers in certain parts of the world were treated to a one-in-150-year triple celestial today.
A blue Moon - a second full moon in the same calendar month - rose above the horizon.
It coincided with a super moon, which is the point when a new or full moon occurs at the same time as it is at or near its closest approach to Earth in a given orbit.
As a result it appeared around a third brighter and 14% bigger than normal.
Normally there is only one full moon every month, but we already had one on New Year's Day.
Unusually, the first two phenomena coincides with a lunar eclipse.
But it is not visible from Ireland, with only those in parts of the US, Middle East, Asia, eastern Russia, Australia and New Zealand able to see it.
A lunar eclipse is caused when the Earth's natural satellite passes into the Earth's shadow.
During this time the moon takes on a reddish tint known as a blood moon, making it a "Super Blue Blood Moon".
The last time this so-called trifecta took place was in 1866.
Here the 'Super Blue Moon' is visible since the moon rises after 5pm, and remains visible until around 8am on tomorrow, with the best viewing time sometime after midnight.
The last time a blue moon was visible in Ireland was three years ago in July 2015, with the next one due on 31 March.
The next lunar eclipse visible from here will be on 27 July.
