The supermoon will appear 14 percent larger and 30 per cent brighter than normal - the outcome of a cosmic quirk as the moon orbits within about 222,000 miles (357,000 kilometers) of our planet.
Some viewers may think the shining orb looks more dazzling, but it's actually an optical illusion.
The glowing disc is simply larger on the horizon next to trees and buildings.
But don't worry if you missed it. The supermoon's effect should still linger until at least Tuesday.

And the largest supermoon until 2034 will roll in on November 14, 2016.
