Three separate celestial events — a supermoon, a blue moon and a full lunar eclipse — will occur simultaneously on January 31.
Just weeks after 2018’s first supermoon of January 1 and 2, this astronomical rarity of events is being called a super blue blood moon eclipse.
This particular blue moon will likely look red in some areas, because of the total lunar eclipse which can give the moon a red tinge, giving it the name blood moon.
This confluence of events has not happened since the second half of the 19th century. And January’s blue moon will be followed by another blue moon in late March.
They are also in a supermoon trilogy, which began last month. The phenomenon “supermoon” occurs when the moon becomes full on the same day it is at or near its closest point in its orbit around Earth.
NASA said this year’s first supermoon, which illuminated skies across the world, was the “biggest and brightest” one for 2018.
It appeared 14 per cent bigger and 30 per cent brighter than the supermoon on July 27 last year, with pictures of it posted on social media by people around the world.
“once in a blue moon”.
Even rarer is the fact there will be two blue moons in the first quarter of 2018, and they are in a series of three supermoons.
