The final full moon of November has been a spectacle to marvel with the added bonus of a crepuscular lunar eclipse, less easy to see but equally dazzling.
This full moon is called Cold Moon, Frost Moon, Winter Moon, Beaver Moon, Oak Moon, Moon Before Yule, Child Moon, Kartik Purnima, Karthika Deepam and Tazaungdaing Festival Moon, and Ill Poya, according to various world customs, calendars and legends.
Among those many names some are better known such as the ‘beaver moon,’ which comes from a Native American tradition associated with the time when beavers finish building their lodges made of branches and mud to prepare for winter.
It’s also well known as the full ‘cold moon’, ‘winter moon’ and ‘frost moon’ due to the long, cold nights of November.

“As the full moon before the winter solstice, an old European name for this moon is the Oak Moon,” Nasa explains, “a name that some believe ties back to ancient druid traditions of harvesting mistletoe from oak trees first recorded by the Roman historian Pliny the Elder in the 1st century CE.”
Penumbral lunar eclipse
As explained by Nasa, the lunar eclipse accompanying the cold moon was at its fullest early on Monday morning, November 30, when it was “close enough to opposite the Sun that it passed through the partial shadow of the Earth, with 83% of the moon in the partial shadow.”
The phenomenon known as a penumbral lunar eclipse, the last of the year, is a celestial occurrence during which the moon dips behind Earth’s faint, outer shadow, or penumbra. This causes the moon to look darker than normal.
Not as dramatic as total or partial lunar eclipses, the Penumbral eclipses “are slight, verging on imperceptible in some cases,” Jackie Faherty, an astrophysicist at the American Museum of Natural History, told the New York Times.
The Beaver Moon has been full for three days starting Saturday night through Tuesday morning.
