There's going to be a legitimately good reason to howl at the moon on the evening of Sunday, Jan. 20 (or the early morning of Monday, Jan. 21 in Europe).
Don't worry, you're not going to grow fur or claws. It's just some rare cosmic geometry that will turn a big ol' full moon a spooky shade of crimson for a spell.
Three elements make a "super blood wolf moon," but the part that makes it so rare it happens only three times this century is the least impressive.
A "wolf moon" is simply the folk name for a moon that happens in the month of January.
Take that away and you've got a super blood moon, which is a total lunar eclipse that happens at "perigee syzygy."
I know some people mistrust words like syzygy without any proper vowels, so let's stick with supermoon from here on.
