The final supermoon of 2025 is almost here, and it's a celestial event you won't want to miss! But why is this full moon so special? And what's the story behind its intriguing name?
December's Full Cold Moon: A Rare Triple Treat
On December 4th, the Full Cold Moon will grace the skies, marking the third supermoon of the year. But here's where it gets fascinating: it's the last of a rare triple-supermoon sequence, with the first two occurring in October and November. And if you include the first full moon of 2026, it's a quadruple treat!
A supermoon occurs when the full moon coincides with its closest approach to Earth, known as perigee. This proximity makes the moon appear larger and brighter, creating a stunning visual spectacle. But don't be fooled by the name; supermoons are not as rare as one might think, with three or four occurring annually. However, having three in a row is less common and a treat for skywatchers.
Moonrise and the Night Sky Show
On December 4th, the full moon will rise in the northeastern skies during the afternoon, at 14:52 GMT in London, and slightly earlier or later in other UK cities. As the moon ascends, it will form a celestial triangle with the Pleiades star cluster and the bright star Aldebaran. Jupiter will also be visible nearby, along with the winter constellation Orion the Hunter, adding to the cosmic display.
Clouds, Mist, and Frost: Will the Skies Cooperate?
While the moon will be visible for several hours after moonrise, the weather may play a role in the viewing experience. A band of cloud and rain is forecast to move across the UK on Thursday, potentially affecting visibility in northern and eastern Scotland and eastern England. However, clear skies are expected to develop overnight in many areas, although widespread mist and fog could form, creating a mysterious atmosphere.
The Cold Moon: A Name with Ancient Roots
The name 'Cold Moon' has a rich history, rooted in ancient traditions. Each full moon of the year has a unique name, dating back to a time before the Gregorian calendar. These names were given to mark the changing seasons and guide activities like hunting and harvesting. December's full moon, occurring near the winter solstice, signifies the beginning of winter and has also been called the Long Night Moon and the Moon before Yule.
And the lunar spectacle doesn't end there! The next full moon, on January 3rd, 2026, will be the Wolf Moon and, you guessed it, another supermoon. So, mark your calendars for this extraordinary celestial finale to 2025 and the beginning of a new year of lunar wonders.
