An NBC Palm Spring Celestial Heads-Up: A Blue Moon!

Astronomically speaking, a 'Blue Moon' is a somewhat rare occurrence when there are two Full Moons in a single calendar month. The first was on May 1... the second will happen on Sunday, May 31. The Coachella Valley will be under clear skies this weekend for perfect Lunar looking!

Because the lunar cycle takes about 29.5 days to complete, this extra full moon in a single month occurs only once every 2 to 3 years.
