People across North America will soon be able to get the glimpse of a supermoon eclipse, which happens when a supermoon coincides with a lunar eclipse. Dr. Paul Sutter speaks with NBC News’ Savannah Sellers about when to see the moon and when the eclipse will begin.

A partial lunar eclipse will coincide with this week's Harvest Moon, which also happens to be an exceptionally bright and large supermoon.

The full harvest supermoon shone brightly in the night sky Tuesday evening. A partial lunar eclipse, with a “bite” taken from the moon, was also visible.

A partial eclipse of the supermoon was visible across the East of England on Tuesday night. This month's full moon, known as the Harvest moon, is the second of four supermoons expected this year. Full supermoons occur when the orbit of the moon is at "perigee" - the closest point to Earth in its orbit - which makes the Moon appear bigger and brighter in the night sky.

The skies will light up Tuesday night with a double lunar phenomenon: the Harvest supermoon and a partial lunar eclipse. Supermoons are full moons that appear larger because they happen in tandem with the lunar orbit's closest approach to earth.
