Rare 'blue supermoon' total eclipse to occur in Singapore on 31 January

The second one is marked by a blue moon. Such an event occurs whenever the moon gets to its closest point to Earth.

Supermoons happen when a full moon coincides with the moon's perigee - a point in its orbit at when it is closest to Earth. For the first time in 150 years, we will witness again a Super Blue Blood Moon.

It will be a total eclipse that involves the second full moon of the month, popularly referred to as a Blue Moon.

SOMERSET skygazers were treated to "the biggest and brightest" supermoon of the year as it rose across the United Kingdom on New Year's Day. However, you might be lucky enough to watch a part of it in Hawaii and Alaska. This year, however, will see two occurrences of two full moons in a month, with the second blue moon occurring on 31 March. The moon rotates around the Earth every 27.322 days, and we get a new full moon approximately every 29.5 days (those numbers don't match exactly due to elliptical orbits).

There's still one thing to explain, namely the blood moon denomination. This only happens every two to three years on average, giving rise to the saying "once in a blue moon".

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.

"The moon will lose its brightness and take on an eerie, fainter-than-normal glow from the scant sunlight that makes its way through Earth's atmosphere", according to NASA. Usually, there's only one full moon per month but, sometimes, once every two and a half years, two such events happen in the same month. Before 2017, there was an 8 percent partial eclipse on December 31, 2009, but, for a total eclipse of a Blue Moon, we have to go all the way back to March 31, 1866. Other regions will be able to see some parts of the eclipse. The partial eclipse begins 11:48 Universal Time (UT), and the total eclipse begins at 12:52 UT and reaches it's maximum at 13:30 UT.

The Pacific Ocean will be turned towards the Moon at the time and the eclipse will take place during the middle of the night.
