Residents get a glimpse of the 'supermoon' Sunday night

But that doesn't mean this weekend's supermoon won't be attractive - expect a full moon at least 7% bigger and 16% brighter than usual.

Supermoons occur roughly once a year.

However, the moon will reach its closest point to the earth at 9am GMT on 4 December when it will come within just 222,443 miles of the earth. Based on the moon's rotation this month's full moon - which is also being called the Cold Moon - will be at its closest point to Earth, creating the Supermoon.

CT residents will have their eyes peeled to the sky Sunday night as the "supermoon" makes its only appearance in 2017.

When's the best time to view the supermoon?

Time your viewing for just after local sunset, National Geographic suggests, when the "moon illusion" will make the orb look especially large and vibrant.

The supermoon which was last seen on November 14, 2016 is set to re-appear tomorrow evening on December 3. This is quite a rare sight however and only occurs about one in every 14 full moons.

Each month the moon rotates around the earth in an ellipse rather than a flawless circle.

If you're unable to see the supermoon, you won't have to wait long for another opportunity.

Skywatchers and stargazers have three opportunities to see a supermoon between Sunday and January 31. You can also watch a livestream from the Virtual Telescope Project.

The full moon will begin at 10:36 a.m., Sunday, in CT.

An image of the moon taken by NASA's Lunar Reconnaissance Orbiter is shown in two halves to illustrate the difference between the apparent size of a supermoon (left) and a "micromoon" (right). In fact, the supermoon slated for January 31, 2018, will be both, making it a Super Blue Moon.
