In a rare occurrence, a blue supermoon is predicted to be among the biggest and brightest moons of the year and will light up the sky on Monday.

The name "blue moon" refers not to the colour but to the month that the full moon occurs each year.

Usually occurring every two or three years, blue moons only happen once, but in 2018 there were two, albeit remarkably close to each other.

In 2037, there will be a second blue moon in a single year.

The moon has also been called the green corn moon, the grain moon, and the red moon for the reddish colour it often takes on in the summer haze.

The supermoon means Earth’s satellite is closest to the planet.

During a supermoon, the moon appears up to 14% bigger and 30% brighter compared with when it is furthest away.

The term supermoon was coined by astrologer Richard Nolle in 1979 as either a new or full Moon that occurs when the Moon is within 90% of its closest approach to Earth.

This will be the first of four consecutive supermoons this year, with the full moons in September and October virtually tied for the closest of the year.

The moon will rise at about 7.26pm, and the best time to catch a glimpse is when conditions are best suited to a clear sky.

This means low cloud cover, favourable weather and no obstructions on the horizon, such as buildings or trees.
