It hasn't happened in almost 400 years, but is happening TONIGHT: the incredibly rare combination of a full moon, the winter solstice, and a full lunar eclipse. 1638 was the last time the world saw this phenomenon. And I'm betting they thought it was witchcraft or something
Locally, it is supposed to be between 2AM and 3AM. Get yourself some hot (spiked) cider and some mittens, and catch the universe putting on a light show. Er, I guess a "lack of light" show.
