The Rare Super Blue Moon Rises Tonight!

How rare is the Super Blue Moon and why do they call it Blue Moon when it wont be blue?

Well its a supermoon, which occurs when the moon appears larger than usual, and a blue moon, or the second full moon in a month.

According to NASA, a blue moon only occurs once every two or three years on average—and a blue moon that is also a supermoon is even rarer.
Tonight's moon should appear a good 7% larger than the average full moon so eyes on the skies tonight for what should be a picturesque event till some time 2024.
