Halloween’s rare blue moon will appear tomorrow night after 19 years
On Halloween, a rare blue moon will appear in the sky for the first time since 2001. A blue moon occurs when there is more than one full moon during a month. NASA says it coincides with Halloween every 19 years. The moon isn’t really blue, but it will be in full bloom to make things a little spookier on Halloween. According to NASA, the next time a Blue Moon and Halloween coincide will be in the year 2039.
NASA explains in its Blog that the Blue Moons will occur approximately every two and a half years. After 2020, there are blue moons in August 2023, May 2026, and December 2028. On average, the Moon is full on Halloween every 19 years, a period known as the Metonic cycle. The Blue Moon comes after the October Harvest Moon that fell on October 2, and theoretically means the time to start storing for the winter.
According to FarmersAlmanac, the Halloween Blue Moon in 2001 was only seen in the Central and Pacific time zones. This upcoming Blue Moon will appear in all time zones, making it even rarer. The report says that a Halloween full moon had not appeared for everyone in all time zones since 1944.
While the most common definition for a blue moon is when two full moons appear in a single month, the second is called the ‘blue moon’. However, there is an alternate definition that says that when there are four full moons in a single season, the third is considered a blue moon.
“The Blue Moons have no astrological significance. However, the fact that the full moon is happening on Halloween is significant. Full moons are a time when we get a little help seeing in the dark. It is a very significant full moon, and it is happening four days before the elections and you are sitting next to a planet with turmoil, change, surprise, excitement: Uranus. Chani Nicholas, astronomer, saying New York Times, adding that it is a good time to get rid of the things we don’t need.
