Yeah, 'blood mood' is just a more dramatic way of saying 'total lunar eclipse' because the moon turns a reddish brown color when fully eclipsed. I guess it sounds more exciting to call it a 'BLOOD MOON' It's only the 4th one we've had in the last year and a half.

Still pretty cool to watch though. Now we have to wait until January of 2018 to see the next one.
