We've already seen a handful of impressive lunar events this year: January's Super Blood Wolf Moon, February's Super Snow Moon, March's Super Worm Moon, and April's Full Pink Moon all had eager stargazers looking toward the sky. Now, May is going to continue the streak with a Full Flower Moon, otherwise known as a Seasonal Blue Moon.
Here's what to know if you want to see it for yourself.
Where does the Full Flower Blue Moon get its name?
A Blue Moon rarely appears blue in the sky, and the name actually has little to do with its color.
Usually, a full moon occurs just once a month. Sometimes-about every three years or so-one month will have two full moons. This phenomenon is what we call a Calendrical Blue Moon. But that's not the case this May, which brings us to the alternate definition of a Blue Moon. According to the Farmers' Almanac, each of the four seasons typically contains three full moons. However, sometimes a season will have four. When that happens, the third full moon of that season is referred to as a Seasonal Blue Moon.
Additionally, each month's full moon is given a name based on what happens during that time of year. Because flowers usually come into bloom in May, its full moon is also known as the Full Flower Moon.
When can you see the Full Flower Blue Moon?
May’s Flower Moon officially turns full on Saturday, May 18, 2019, at 5:11 p.m. ET. Your best chance of catching it is later that night, when the sun has set and the moon will still be high in the sky.
