Once in a Blue Moon

Halloween 2020 will reveal a rare blue moon

Get out your broom sticks and bat wings. The night sky on October 31 will reveal a rare and spooky sight: a Blue Moon will take place on Halloween for the first time since 1944. 

A Blue Moon is described as being the second full moon of any given month, the next of these rare moons is set to happen this Halloween.  When a full moon occurs in the beginning of the month, a Blue Moon will appear on one of the last days. These are seen as rare and special because they happen no more than once every two years. 

“…Blue moon is special because it is the ‘extra’ Moon in a season with four full moons,” www.spaceplace.nasa.gov says. 

The term “Blue Moon” may lead some to believe that the moon will cast a bright blue hue over the earth, but that is not the case.  The special moon gets its name from an old folklore, that comes from a time when the sky was so clear, that the moon was actually seen as blue. This of course, has changed, as the moon appears to the eye as a grayish color. 

“But will it really be blue? Probably not. The date of a full moon, all by itself, doesn’t affect the moon’s color. The moon…  will be pearly-gray, as usual,“ Nasa said. 

The Blue Moon isn’t the only spooky phenomenon happening on the 31st, the “Halloween Full Moon” is also taking place for the first time in 19 years. This simply means that a full moon falls on Halloween. But, the combination of both Blue and Halloween moons occurring on the same day is so rare that the last time it happened was 1944. 

“Halloween full moons occur every 19 years in what’s known as a Metonic cycle, according to the Old Farmer’s Almanac, and it won’t happen again until 2039, hence the cliche, ‘once in a blue moon.’ But a blue moon on Halloween? That only happens three or four times in a century.”  www.patch.com said.

Take a moment to look up at the sky this Halloween. It may look normal to most, but a full, Blue Moon occurring on Halloween Night may not happen again for a long time.
