The Beaver Moon

November 28 marks the last full moon before the formal arrival of winter.  It is known in folklore as the Beaver Moon.

According to the Farmers’ Almanac, the Beaver Moon marked the time for setting beaver traps so there would be a sufficient supply of fur for the upcoming winter months. The beavers themselves are preparing for winter around this time of year. This full moon has also been called the frosty moon.

The November 2012 full moon will be the smallest of the year. It will also be accompanied by a subtle penumbra eclipse, during which the moon passes through the light penumbral shadow surrounding the umbra. The umbra is the darkest shadow of the moon cast by the Earth.

A penumbral lunar eclipse is not as obvious as an umbral eclipse of the moon because the moon does not pass directly across the Earth’s shadow. Although the penumbral eclipse will last for over four and one-half hours, viewers will only be likely to notice a slight shading on the north side of the moon for up to an hour or so, centered at the time of greatest eclipse (14:33 UTC).

The farther west and north you live in North America, the better your chances of catching the subtle shadow on the moon before dawn on November 28. The farther east or north you are in the world’s Eastern Hemisphere, the better your chances of seeing the penumbral eclipse after nightfall on November 28. It will take until at least 70% of the moon’s diameter is immersed within the Earth’s penumbral shadow before the eclipse even becomes noticeable. At the time of greatest eclipse on November 28, the penumbral shadow will cover nearly 92% of the moon’s diameter.

No penumbral eclipse will be visible for the east coast of the United States, central and South America, and western parts of the African continent.
