Look up tonight! Full Cold Moon will light up skies this evening - so when is the best time to see it?

  • Around midnight tonight the Cold Moon will reach its maximum illumination 
  • This will be the last chance of 2023 to see a full moon light up the night sky  

The Christmas festivities might be dying down, but there is one last treat in store for budding sky watchers.  

Be sure to keep an eye on the sky this evening as the full Cold Moon hits maximum illumination.  

This is the last chance to see a full Moon this year and will be a great opportunity to spot some of the Moon's geological features with the naked eye. 

From the UK, the Moon will rise in the Northeast at 2:52pm GMT shortly before the Sun sets at 3:57 pm later today. 

The Moon will then set in the Northwest at 9:07am GMT, meaning it will be in the sky all night.

You might have already seen the Moon appearing large and bright in the sky on Boxing Day as the full Moon first rose.

But if you were already taking a well-earned Boxing Day nap by that point there is no need to worry as tonight's display will be even brighter. 

Technically, the Moon is only 'full' when it is exactly 180 degrees opposite the sun for a brief moment. 

However, the Moon appears full from Earth for the two days either side of this instance. 

This means that tonight will be your last chance of the year to see a full Moon.  

You won't need any special equipment to get a great view of the Moon tonight, but to get the best view try and catch the Moon at peak illumination.

At 00:33 am GMT in the UK or 7:33 p.m. EST in the US, the Moon will reach its maximum brightness, high overhead in the winter constellation of Orion.

Alternatively, try and catch the Moon just before or after it rises to get a great view of it over some local landmarks.

This will also take advantage of the 'Moon Illusion', an optical illusion making the Moon appear larger than normal while close to the horizon.

Even with the naked eye viewers will be able to spot the Moon's 'seas'.

These darker areas do not contain water, as early astronomers believed, but are actually planes of cooled lava big enough to be seen from Earth. 

For example, tonight any stargazer should easily be able to make out the Mare Tranquillitatis or sea of tranquility. 

But for anyone who might be testing out a new telescope or pair of binoculars tonight, Jessica Lee, astronomer at the Royal Observatory Greenwich, told MailOnline that the Moon is a great way to practice. 

'If you’ve never used one before, finding something to look at through the telescope is the first challenge,' Ms Lee told MailOnline.

Ms Lee adds: 'Try starting with something easily seen with your eyes, and don’t be discouraged if it takes some time to locate it with the telescope as it can be tricky. 

'Think about your night vision – go somewhere away from streetlights where possible, switch to night vision mode on any apps you’re using if they have the option, and turn off any torches or other light sources.'

However, if you are planning on stepping out for some Moon watching tonight make sure to prepare for bad weather. 

The Met Office forecast predicts that there will be heavy rain over the North of England and Scotland

Ensure you are dressed appropriately and are prepared for some wet conditions.  

The Met Office has issued yellow weather warnings for large parts of the country including Scotland, the South of England, Wales, and the North of England.

Heavy rain and even snow are forecast across Scotland and England with temperatures expected to fall as low as 39°F (4°C).

There are expected to be some breaks in the cloud cover by midnight tonight so there will be some opportunities to get a good view of this dazzling display.

The Cold Moon, sometimes cold the Long Night Moon, gets its name from its proximity to the Winter Solstice.

It is frequently said that this derives from the Native American Mohawk tribe's traditional names for the different Moons of the year.

However, the tradition was actually popularised by the American Farmers Almanac and the names are chosen somewhat arbitrarily. 

While the Moon will be large and bright, this is not a supermoon –the name for a full moon during the closest point in its orbit around Earth. 

Because the Moon's orbital path is elliptical, it gets closer and farther from Earth during the lunar cycle. 

At its peak tonight, the Moon will be around 239,806 miles (385,930km) away from Earth.

However, a full Moon is only considered a supermoon when it is less than 223,693 miles (360,000km) from Earth.

During a supermoon, when the Moon is at its closest point to Earth, the Moon may appear up to 14 per cent larger.

The next chance to catch a supermoon will be on September 18, 2024, according to Royal Museums Greenwich. 

Full moon, supermoon, Cold moon: What's the difference?  

A FULL MOON  is the phase of the moon in which its whole disc is illuminated.

During the 29.5-day lunar cycle, we observe a new moon (with 0 per cent illumination), a waxing moon (when the amount of illumination on the moon is increasing), a full moon (100 per cent illumination) and then a waning moon (when its visible surface area is getting smaller).

Because our modern calendar isn't quite in line with the Moon's phases, sometimes we get more than one full Moon in a month. This is commonly known as a blue moon. 

Meanwhile, a SUPERMOON  is when the full moon nearly coincides with perigee – the point in the orbit of the moon at which it is nearest to the Earth.

This means a supermoon can appear as much as 14 per cent larger and 30 per cent brighter than when it's furthest away from Earth. 

There are about three or four supermoons per year, most astronomy websites claim, and they happen at different times each year. 

In a nutshell, a supermoon is a full moon. But it's bigger and brighter than a normal full moon. 

Lastly, COLD MOON simply refers to the time of the year the full moon is appearing.

In December, it's known as Cold Moon because nights at this time of year are the longest and temperatures the most frigid. 

Other months of the year correspond to different nicknames - so January is Wolf Moon, February is Snow Moon, March is Worm Moon, April is Pink Moon, May is Flower Moon, June is Strawberry Moon and so on.  

Full moon names were historically used to track the seasons and therefore are closely related to nature. 

The full list of full moon nicknames: 

January: Wolf Moon because wolves were heard more often at this time.

February: Snow Moon to coincide with heavy snow.

March: Worm Moon as the Sun increasingly warmed the soil and earthworms became active.

April: Pink Moon as it heralded the appearance of Phlox subulata or moss pink – one of spring's first flowers.

May: Flower Moon because of the abundance of blossoms.

June: Strawberry Moon because it appeared when the strawberry harvest first took place.

July: Buck Moon as it arrived when a male deer's antlers were in full growth mode.

August: Sturgeon Moon after the large fish that was easily caught at this time.

September: Corn Moon because this was the time to harvest corn.

October: Hunter's Moon after the time to hunt in preparation for winter.

November: Beaver Moon because it was the time to set up beaver traps.

December: Cold Moon because nights at this time of year were the longest.
