Seasonal Blue Moon: Understand the Rare Occurrence on Sunday – 08/19/2021

There will be a rare lunar event on Sunday (22): a “seasonal blue moon,” which occurs every two and a half and three years, according to the US space agency NASA.

Records of Blue Moons have existed for a long time in history. First Use of “Blue” Moon“(in English) dated 1528 according to NASA. In the 1940s, the term “blue moon” was also used to refer to the second full moon recorded in the same month, which is difficult to occur.

The phenomenon is also known in the United States as “sturgeon moon”, in reference to the fish of the same name. Native tribes made this reference due to the fact that this period was good for catching large fish in the lakes – sturgeon once measured 5.5 meters.
