The first full moon of the new year, January's Wolf Moon. It’s officially full at 4:07p NM time this afternoon.
At the same time, the moon will be on the far side of Earth and at its furthest from the sun, making it a "micromoon," the opposite of a supermoon.
Old Farmer's Almanac states that the name for January's full moon, the Wolf Moon arises due to the fact it was seen at times of the year when wolves could be howling outside villages as a result of hunger.
