Watch Live: The Largest Supermoon In 68 Years Appears Tonight

Don’t miss the biggest supermoon in a generation this Monday.

Skywatchers will have an opportunity to witness the biggest and brightest supermoon in a generation on Monday when the full moon makes its closest approach to Earth in more than 68 years.

A supermoon occurs when a full moon or new moon coincides with perigee, the point in a moon’s orbit when it is closest to Earth. Typically what are described as supermoons are full moons which occur within 90% of its closest approach to Earth.

The moon’s orbit around Earth is elliptical, meaning that it is not a perfect circle. There are times in the moon’s orbit when it is further away from Earth and times when it is closer. Supermoons that come this close to Earth are a very rare sight to behold. The last time a supermoon was this close to Earth was in 1948 and it won’t happen again until 2034.

Supermoons, also known as full moons at perigee, can appear up to 14% closer than at apogee, the point at which the moon is furthest from Earth. When a full moon is at perigee, it reflects more sunlight and can appear up to 30 percent brighter than usual.

This supermoon is also unique in that it is also the second in a series of three supermoons appearing in three consecutive months, the first occurring on October 15, 2016 and the next to appear on December 14, 2016.

The moon will achieve perigee at 6:22 a.m. EST and will become “full” at 8:52 a.m. EST on Monday, November 14, 2016.

The Slooh Community Observatory will be providing a livestream of the event for those who are unable to view the supermoon due to poor weather conditions. Slooh’s webcast begins at 8 p.m. EST on Sunday, November 13, 2016.
