For the next three nights we can enjoy the Cold Full Moon. The actual Full Moon is Thursday December 12th at 12:12 am (EST), which is really Wednesday night. So the Full Moon is on 12-12 at 12:12 am? Tonight the almost Full Moon rises at 4:04 pm, the real Full Moon rises Wednesday at 4:44 pm, and the just past Full Moon rises at 5:31 pm on Thursday. The Full Moon in December is one of the highest in the sky Full Moons of the year. This is because the Moon is opposite the Sun in the sky when it is Full, that means the Moon will take the same path across the sky tonight, as the Sun will follow 6 months from now during the summer when the Sun is high in the sky. December’s Full Moon is known as the Full Cold Moon by Native Americans because December is the month that starts the coldest part of winter season.
