What is the true definition of a blue moon?

The "blue moon" reference is applied to the third full moon in a season with four full moons, thus correcting the timing of the last month of a season that would have otherwise been expected too early. This happens every two to three years (seven times in the Metonic cycle of 19 years). wikipedia.orgBlue moon

The stunning phenomenon only happens once in almost every three years - but Americans will be able to catch a glimpse of a one tonight.

People living in the US will be able to see a full Blue Moon overnight, with it reaching its highest point in the sky at about 1.04am ET, according to NASA.

It will reach its peak illumination at about 8.02am on Sunday.

But there's a catch, as - despite the name - blue moons of this kind aren't actually blue.

The confusion is because the term originates in "blewe", the old English word for "betrayer".

But - even more rarely - a full blue moon will appear blue when "volcanic eruptions or forest fires send lots of smoke and fine dust into the atmosphere," according to Sky & Telescope.

In recent years, the term blue moon has come to refer to the second full moon in a month, but tonight's sky phenomenon will be in accordance with the original definition of the phrase - the third full moon in a season containing four full moons, rather than the usual three.

"The first recorded use of "Blue Moon" in English dates from 1528.

"Since the 1940s the term "Blue Moon" has also been used for the second full Moon in a month that has two full Moons."

The next blue moon of this kind will not shine in the sky until 2024, as these only come about once every 2.7 years on average.

This weekend's blue moon will also be called the Sturgeon Moon.

The Sturgeon Moon is a common name for August's Full Moon because North American fishing tribes would see the appearance of lots of sturgeon fish around this time of year.
