The supermoon will peak in the night sky at 9.24pm EST (2.24am GMT Tuesday January 2).
The peak comes hours after it reaches its perigee – its closest point to Earth for the month at 4.54pm EST (9.54pm GMT January 1).
According to EarthSky.org, the moon will be able 221,559 miles (356,565 kilometres) from Earth at its perigee.
NASA has said a supermoon can appear as much as 14 percent bigger and 30 percent brighter than when a full moon is at its farthest distance.
It is the second supermoon in a ‘supermoon trilogy’, the first supermoon appeared on December 3 2017 and the last in the series will appear on January 31.
The January 31 supermoon is the second full moon of January, making it a Blue Moon and it will occur during a total lunar eclipse.
Tonight’s full moon is known as a ‘Full Wolf Moon’ – a name coined by early Native American tribes as it was the time of year when hungry wolf packs howled outside their camps.

When is the next supermoon?
Supermoons happen when a full moon approximately coincides with the moon’s perigee or a point in its orbit at which it is closest to Earth.
In 2018, there will be one other supermoon on January 31 and it will be the second full moon of January, making it a Blue Moon and it will occur during a total lunar eclipse.
“The lunar eclipse on January 31 will be visible during moonset. Folks in the Eastern United States, where the eclipse will be partial, will have to get up in the morning to see it,” Noah Petro, a research scientist from NASA’s Goddard Space Flight Centre said.
There will be a total lunar eclipse on January 31 in North America, Asia, and Australia, among other places, which will turn the blue moon red.
NASA has billed the January 31 moon a “super blue blood moon.”
