What is a snow moon and when can I see it?

Clear skies on Sunday night meant that budding astronomers were able to see the spectacular 'snow moon' across much of the UK. Although the full moon "technically" occurred last night, at 6.28pm to be precise, it'll still appear full until Wednesday morning.

Why do we name full moons?

All full moons are given names, which are often linked to the time of year they occur. The names were given by Native Americans in North America in a bid to track the seasons.

There are some variations in the list, depending on where you look, as different tribes and settlers around the world created their own. However, the most common is the Farmers Almanac list, which we have adopted in the UK.

Why is it called a snow moon?

The full moon that occurs in February is referred to as the snow moon because the heaviest snow fall in North America usually occurs during this month. Harsh weather conditions of freezing temperatures, strong winds and heavy snowfall made hunting in these areas very difficult. As a result, some colonies referred to this moon as the hunger moon.

February's snow moon will be the smallest of 2023

It may seem hard to believe but just like we get supermoons, we also get the opposite, called micromoons. The moon's orbit around Earth isn't a perfect circle, it's more of an oval - known as an "elliptical orbit". Therefore some months it's closest to the Earth (called perigee) and other months it's actually further away (known as apogee).

February's moon was furthest from Earth on 4th February at 9am, with a distance of 252,171 miles (405,830 km).

Both January and February's 2023 moons were a micromoon, but February's was the furthest away.

Unlike a supermoon, where the moon appears 30% brighter and 14% bigger, a micromoon appears 14% smaller and "less bright", although it's really difficult to the naked eye.

Can I still see this year's snow moon?

You still to have an opportunity to see this year's snow moon - it will appear full until the morning of the February 8 2023.

Fortunes are split weather-wise for astronomy enthusiasts, with the south experiencing clearer skies over the coming nights. Meanwhile, the northwest often stays cloudy, which will shroud the view.

But don't worry, if you miss it, the next full moon will be March 7, although that will be a worm moon, which is a whole other story...
