Traditional names for January Moons are: Wolf Moon, Buck Moon, Thunder Moon, Wort Moon, and Hay Moon!

The 2020 Wolf Moon Penumbral Eclipse, one of 13 full moons this year, though not visible during the daylight hours in the America's, will be visible in Europe, Africa, Asia and parts of Australia! In the case of a penumbral lunar eclipse, the moon is covered by Earth’s lighter or outermost shadow (the penumbra) as opposed to its main shadow (the umbra). If you are in the right spot for viewing you will notice a dark shading on the moon’s face. 🌚

For millennia, people across Europe, as well as Native American tribes, named the months after features they associated with the seasons in the Northern Hemisphere, and many of these names are very similar or identical. 

Some years have 13 Full Moons, which makes at least one of them a Blue Moon, as it doesn't quite fit in with the traditional Full Moon naming system. However, this is not the only definition of a Blue Moon.

About every 19 years, there is no Full Moon in February. This is one of several definitions of the term Black Moon. The other definitions refer to a New Moon which does not fit in with the equinoxes or solstices, similar to a Blue Moon.

many of these ancient month names have been adopted as names for the Full Moon of each month. A common explanation, published in the Old Farmer's Almanac, is that Colonial Americans adopted Native American names and incorporated them into the modern calendar. However, it some Full Moon names we use today also have Anglo-Saxon and Germanic roots.

Occasionally, the full moon is eclipsed by the earth's shadow.  In general, 

the umbra, penumbra and antumbra are three distinct parts of a shadow, created by any light source after impinging on an opaque object. 

Lunar eclipses occur when the Moon passes through the shadow of the Earth.  They only occur during a full moon when the Earth is between the moon and the sun.  There can be total, partial, and penumbral lunar eclipses. 

Similarly, solar eclipses occur when the Earth passes through the Moon's shadow​.

This tartan was created by designer Carol A.L. Martin, to mark the two full moons of December 2009.
