Tonight is the first of two December moons.
The Full Cold Moon; or the Full Long Nights Moon - December-During this month the winter cold fastens its grip, and nights are at their longest and darkest. It is also sometimes called the Moon before Yule. The term Long Night Moon is a doubly appropriate name because the midwinter night is indeed long, and because the Moon is above the horizon for a long time. The midwinter full Moon has a high trajectory across the sky because it is opposite a low Sun.
It's also the inaugural ride of the SS Raleigh, a converted 10 speed circa "88" beast.
The second full moon of the month is on the 31st, and the second full moon of any month is called the Blue Moon.
