June will have two full moons

Across Asia, the 1st and 2nd will be the first night of the 2 full moon nights of June. Some calendars and almanacs note that when the full moon appears twice a month, that second moon is called "blue moon" . The same thing happens to people who live in Europe, Africa and Australia. In North America, the "blue moon" occurs earlier, on May 31.

Of course, the full moon in the second period is no different from any other full moon. However, the moon can change colors in certain conditions.

For example, wildfires or volcanic eruptions often cause the atmosphere to become dense with ash, causing the moon to look bluish, even purple. This has been observed when dust from Western Canadian wildfires occurred, creating a blue moon across North America in late September 1950. After the eruption of the Pinatubo volcano in the Philippines In June 1991, there were reports of the blue moon (even the blue sun) around the world.

The moon may be " green " because of the dusty atmosphere that disturbs the image (Photo. Photogalaxy.com).

The concept of " in a blue moon " was first recorded in 1824 and referred to an unusual event, though not really rare. However, two full moon periods in a month are not as rare as people think. In fact, it occurs on average every 32 months. And in 1999, this phenomenon also appeared only 3 months apart!

It was not until 1999 that the origin of the term " blue moon " was discovered. It was from 1932 to 1957, in Almanac Maine Farmers, that if one of the four seasons (winter, spring, summer or autumn) had four full moons instead of the usual three, the third full moon will be called a " blue moon " or " blue moon ".

But thanks to some translation errors in this tutorial, it is now understood as the second full moon in a month that is defined as a " blue moon ".
