This November brings an epic celestial event – A Supermoon.  Not just any old Moon, the closest, brightest and largest full Moon for 86 years!

Visible to most of the planet, so don’t miss this epic lunar spectacle. 

What is a Supermoon

The term “Supermoon” is relatively new and describes a full Moon that is closer, brighter and apparently larger than normal.

A full Moon occurs each month when the Sun Earth and Moon line up.  The Moons orbit is slightly elliptical, meaning it’s orbit isn’t a perfect circle.  Occasionally when the Moon is full and its near its closest point to Earth (known as Perigee) it can appear up to 14% larger and 30% brighter than normal in the sky. “A Supermoon”.

The Moon in November 2016 will be the largest since 1948 and the next time its this close will be 2034!  There will be many more supermoons from now until then, but none of them as close.

To a normal passer by who is unaware that there is a supermoon they may not see any difference to any other full Moon, the differences are quite slight. The term can frustrate some as it has attracted a lot of hype implying the Moon is going to appear massive, when in reality there will be slightly noticeable differences.

If you were to look at the Moon when it first rises in the evening and when it’s close to the horizon it can appear much larger than usual. This is known as the Moon illusion and more info can be found here.

When is the Supermoon

November’s full Moon is also known as the Beaver Moon occurs November 14th at 13:52 GMT. It will appear at its fullest/ brightest the evening before or near this time depending on what part of the world you are viewing from. It should look fantastic though a night either side.

Please watch this fantastic video from NASA for more info.

    You say: “… it can appear up to 14% larger and 30% brighter than normal in the sky.” It can appear up to 14% larger than its *smallest* apparent size, so will only 7% larger than ‘normal’, or average size.
