A BLUE supermoon will be visible tonight - a phenomenon which will not happen again until 2037.

The term 'blue moon' refers not to the colour, but instead to the second full moon in a single calendar month.

This does not make it any less spectacular however, as the moon will appear much larger than normal, and we will not see a blue supermoon again in the next fourteen years.

Tonight's blue supermoon is set to rise at around 8pm, and set at 6am the following morning.

Dr Greg Brown, astronomer at the Royal Observatory at Greenwich, says the rare astronomical phenomenon will be best visible at 2:35am, when it is completely lit up by the sun.

However, he also says it is unlikely to be significantly more visible at this time compared to the rest of the night.

As long as the sky is clear, anyone should be able to get a glimpse of the blue supermoon.

For those wanting to make the most of this extraordinary celestial occurence, here are the five best spots in Somerset to see the blue supermoon.

Othery

The parish and village of Othery is situated seven miles east of Bridgwater. 

Home to the Somerset Levels Stargazers club, Othery's location within the Somerset Levels means astronomy lovers can benefit from dark, rural skies at night time due to the lack of light pollution.

Wells

Wells can be easily accessed by most Somerset residents via car or bus.

It was ranked as the fourth best spot for stargazing in the UK due to low light pollution, according to a study by bestgamblingsites.com.

Wells' location on the edge of the Mendip Hills makes for many peaceful spots to view the blue supermoon.

Wellington

The market town of Wellington is an ideal supermoon viewing spot for Taunton residents. It can be reached in just 17 minutes by car, according to Google Maps.

Wellington's rural location once again means low light pollution and dark skies, and its views of the tone valley could make for quite the spectular backdrop to tonight's rare astronomical event.

Porlock Common

For those who like a sea-view, Porlock Common resides just west of Minehead, and is known to be a top-tier spot for stargazing.

Situated in Exmoor National Park, Portlock Common (which overlooks Porlock Bay) is part of an area officially labelled as a Dark Sky reserve.

The Dark Sky website describes Dark Sky reserves as: "Dark “core” zones surrounded by a populated periphery where policy controls protect the darkness of the core."

As well as negligible levels of light pollution, those who choose to view the blue supermoon from Porlock Common will see the moonlight reflecting off the sea water.

Bruton

Located conveniently near to Castle Cary train station, Bruton can be accessed from all over Somerset.

As well as being listed as an area of outstanding natural beauty, the area of Cranbourne which Bruton is situated in benefits from particularly low light pollution as it's part of the Cranbourne Chase Dark Sky Reserve.

More specifically, King Alfred's Tower Car Park is a recognised Dark Sky discovery site, meaning anyone can stargaze there - the perfect spot to see the blue supermoon!
