The December full moon will slowly peek out over the horizon on Sunday December 3, for the first and last supermoon event of 2017.

During this rare spectacular event the moon could swell up to 14-times in size and shine 30-times brighter, according to NASA.

The supermoon will begin to rise in the late afternoon to evening hours when the skies are darkening and the sun is setting.

But those who will not be able to watch the moonrise in person are in luck because robotic telescope service Slooh will livestream the entire lunar spectacle online.

The Slooh Supermoon Challenge will kick off tomorrow on Sunday at 9pm EST (Monday at 2am GMT).

The show promises to “celebrate” the moon and walk the audience through its history.

Slooh teased: “Ah, to be moonstruck, drunk on moonshine, full of restless energy, emboldened by a Full Moon. 

“That is what we want to capture with the Challenge. There’s a reason the full Moon is linked to quirky and peculiar behavior - its intense luminosity draws you outside to wander, question, dare. 

“We challenge you to use this powerful moon magic to connect to your people and the universe. So, what are you doing this Supermoon? Send your video, written thoughts, audio recordings.”

The livestream will be hosted by long-time Slooh astronomers Helen Avery and Paul Cox. 

During this rare lunar event, the moon will reach its point of perigee, when its orbit comes about as close to Earth as it possible.

This happens because the moon’s orbital path is elliptical and not round, forcing to approach and drift away from Earth throughout the year.  

Lyle Tavernier from Nasa's Jet Propulsion Lab explained: "Full moons can occur at any point along the Moon’s elliptical path, but when a full moon occurs at or near the perigee, it looks slightly larger and brighter than a typical full moon. 

"That’s what the term 'supermoon' refers to.

"Because supermoon is not an official astronomical term, there is no definition about just how close to perigee the full moon has to be in order to be called 'super'. 

"Generally, supermoon is used to refer to a full moon 90 percent or closer to perigee."

At perigee, the moon reaches an average distance of 363,300 km from Earth. But when it reaches apogee, its farthest pint from Earth, it sits roughly 405,500 km from Earth.

Slooh said: “While not rare, December’s Supermoon will be the largest one in 2017 - so let’s celebrate it! 

“For much of our history, Full Moons have taken the blame for a whole host of occurrences - insomnia, sleepwalking, pregnancy, menstrual cycles, childbirth, seizures, suicide, accidents, criminal mischief and even transformation into werewolves and selkies! 

“Although modern research hasn't supported these claims, it is undeniable that a glorious and glowing orb in the sky brings magic, leaving one moonstruck: restless, bold, willing to transcend boundaries.”

Viewers are encouraged to share their own pictures and videos from the supermoon rising with the Slooh team.
