SOUTH MISSISSIPPI (WLOX) - Thursday night's sky will bring a blue moon. No, that does not mean that it will be the same color as a blueberry. But, it does mark a special occasion.
Tonight's moon is called a blue moon because it's the second full moon of this calendar month. Usually, each month only gets one full moon. But, because each month is around 30 days long and each full moon occurs about every 29 days, sometimes you can get two in a month.
It's a rare occurrence. And that's where the phrase 'once in a blue moon,' comes from.
July's first full moon took place on near the beginning of the month. July's second full moon will rise in Biloxi's eastern sky around 7:12pm Thursday night which is only 40 minutes before sunset. It sets Friday morning around 6:25am. If Thursday night is too cloudy, you can also catch another glimpse of the full moon on Friday night.

The next blue moon will not happen until 2018.
