We'll be experiencing a "Blue Moon!"
According to folklore, the second full moon in a month (or sometimes the fourth full moon in a season) is called a Blue Moon. It has nothing to do the color of the moon itself.
If you want to check out today's Blue Moon -- the last one you'll see until July 31, 2015 -- you'll have TWO opportunities:
The first will be between 6:30 and 7 a.m., as the moon is setting. (You probably missed that one.
Then later, around 7:13 p.m., you'll get your second chance
As I said, the color of the moon isn't actually blue. If anything, the Friday evening moon will most likely appear an especially brilliant white.
