Have you watched a lunar eclipse before?
This weekend you may have noticed a little difference in the moon; maybe it was a little more clear and shiner than normal? That's called a 'frosty moon,' and it's happening the same weekend the last lunar eclipse of the year is happening.
The eclipse happens Sunday night when you'll see a big chunk of the full moon will be darkened.
November's full moon is known as the 'frosty moon' in parts of Native American lore.
It's also been called the beaver moon, the oak moon, and the mourning moon.
Do you do it from your backyard, or do you have a favorite spot for stargazing?
