December’s Cold Moon: The Last Full Moon of 2024

The last Full Moon of 2024, known as the Cold Moon, will occur on Sunday, December 15, at 4:02 A.M. EST. This Full Moon gets its name because it happens during a time when colder temperatures are prevalent across North America.

The Cold Moon is part of the traditional naming system for Full Moons, which often reflect the seasonal activities or phenomena associated with the time of year. In this case, the cold winter weather is the inspiration behind its name.

Astronomically, the Full Moon occurs when the Earth is positioned between the Sun and the Moon, aligning the three celestial bodies and causing the entire face of the Moon visible from Earth to be illuminated by sunlight. This alignment results in the Moon appearing fully lit in the night sky.

On the evening of December 14, observers can also enjoy other celestial sights. For instance, Jupiter will be visible in the eastern sky, standing between the Moon and Aldebaran, Taurus’ red giant star. Additionally, Mercury will reach its stationary point against the background stars of Scorpius on December 15, marking the end of its retrograde motion and beginning its prograde motion.

In astrological terms, the Full Moon in Gemini on December 15 is significant. It marks a turning point in the monthly lunar cycle, symbolizing culmination, celebration, or release. This Full Moon is also influenced by Mercury’s stationing direct after a period of retrograde, which could bring clarity and breakthroughs in communication and information.

Following the Full Moon, the Moon will transition into its waning gibbous phase, with moonrise and moonset times changing each day. On December 16, the Moon will rise at 5:49 P.M. and set at 8:53 A.M., gradually decreasing in illumination as it moves away from full moon phase.
