But some people will want to check out the moon just because it's, well, huge and gorgeous, and are frantically wondering when is the best time to see the December supermoon. The full "cold moon" that will be rising on Sunday, Dec. 3, happens to be the only visible "supermoon" of 2017. The supermoon can give us a moon that is up to 30% brighter and 14% larger than when the moon is farthest from the Earth.

As the moon orbits the Earth every month, there is a point in every cycle where the moon is closest (perigee) and a point where it's farthest away (apogee). On this occasion, the moon will go fully "Full" at 10:47 a.m. EST on Sunday, December 3, then reach its perigee December 4 at 3:45 a.m. EST.

'Comparing a supermoon with a typical full moon from memory is very hard'. Other native American tribes called it the Long Nights Moon because it occurs close to the winter solstice, the shortest night of the year, The Old Farmer's Almanac explained.

However during a supermoon event the full moon comes up to 90 per cent closer to perigee, thus filling up the skies.

According to National Geographic, the moon will appear seven percent bigger and 16 percent brighter during this year's supermoon.

Skygazers are set to be treated to a "full cold supermoon" this weekend.

So, why is the moonrise the best time to view the supermoon? The two full moons in January 2018 - on January 2 and 31 - also count as supermoons. The moon's elliptical orbit causes its distance from the Earth to vary by 30,000 miles. The moon will look bigger when it is near the horizon and framed with a building or object on the foreground.

The above picture was taken from a west-facing sixth-floor window in my old apartment. You're not going to get a giant moon in your shot, but you can do something more panoramic, including some foreground that's interesting. This produces variations in the moons apparent size and brightness. The only thing that's changed is my view and perception of it. It's more like an oval, so at times it's closer to the Earth than it is at other times. "That means we judge celestial objects that are overhead to be closer than celestial objects on the horizon".
