Don't miss the last 'supermoon' of the year in tonight's sky

At this time, the moon also appears both bigger and brighter than it actually is.

Supermoons occur when the moon is full and also at or near its closest point in orbit around the Earth.

An optical illusion, known as the "moon illusion", makes the moon appear even larger when it is close to the horizon compared to when it is high in the sky.

The moon on Sunday into Monday was 222,135 miles from Earth.

The moon vacillates between 363,000 and 406,000 km in distance from earth.

This year's supermoon appeared bold and bright in the sky overnight.

Sunday's moon is the first of three consecutive supermoons. The relevant term is "perigee-syzygy" and three "perigee-syzygy" has occurred in 2017.

Last year, the supermoon was spotted over other famous Buffalo landmarks including Shark Girl, the Richardson Olmsted Complex and Buffalo City Hall.

Part of it depends on where you're viewing the supermoon.

Tom Kerss, an astronomer at Royal Observatory Greenwich, said the exact moment of full moon - when the moon sits opposite the sun in the sky, which was 3.47pm (10.47am ET) today in the United Kingdom.
