The Supermoon Challenge live stream above will kick off in the wee hours of Monday at 2am GMT (Sunday at 9pm EST), thanks to robotic telescope service Slooh.
The moon will make a close approach to Earth in the late afternoon to evening hours tonight, appearing up to 14-times larger than usual.
Unfortunately this is the first and last supermoon of the year, but observers can look forward to the next two supermoons in January and February 2018.
Amateur astronomers in the UK can expect the moon to rise on the horizon just after 4pm, around the same time the sun sets. Just be sure to catch it before it sets on Monday morning.

Those who would rather avoid the chilly late hours are in luck, because the entire event will be live streamed online.
The Slooh Supermoon Challenge promises to walk its audience through the moon’s history and celebrate its place in science and culture.
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 behaviour – 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.”
Long-time Slooh astronomers Helen Avery and Paul Cox will host the show astronomical tonight.
Viewers are encouraged to send in their own videos and pictures of the moon, as well as any burning questions they might have.
The December full moon will reach its point of perigee tonight, when its elliptical orbit brings it very close to Earth.
Astronomer Karen Stevens explained: “The term ‘supermoon’ is not an astronomical term, but a popular name for when the Moon’s full phase coincides with the point in its orbit that takes it closest to Earth – this is called ‘perigee’.
“Astronomers prefer either perigean or perigee syzygy Full Moon but feel free to call it Supermoon.
“Because the Moon’s orbit around the Earth is elliptical, it is closer to the Earth at some points in its orbit than others.”
The result of this is a dazzling moon which is 14-times bigger and 30-times brighter than usual.
It takes the moon just about 27.3 days to orbit the Earth, and through this time it averages a distance of 384,400 km from the planet.
