One more thing, the blue moon on Halloween will also be the smallest full moon on the year. Also, on the night of the blue moon, the moon will be 14 percent larger in size and its brightness will be more than other days. It was named so because of its close proximity to the autumnal equinox. A blue moon is a rare phenomenon that happens every two to three years when there are two full moons in a calendar month. This is the first time since 1944 according to USAtoday.com who uses information from the Farmers' Almanac for that statistic. But, about every 2 1/4 u00bd years, we get an extra full moon in a season, Nichols said.
But perhaps few people understand how the basis of this odd idiom is actually grounded in an astronomical phenomenon which, by definition, does not occur particularly often.
Halloween may seem extra spooky this year thanks to a full moon. Nonetheless, there are extraordinary circumstances when the same month buys two full moons. Full moons are separated by 29 days, while most months are 30 or 31 days long; so it is possible to fit two full moons in a single month.
Usually, every month has one full moon and one new moon.
He expanded that it is furthermore not feasible to have a full moon in February as it has 28 days, and 29 days during a leap year.
The full moon on Halloween is expected to be visible at 10:49 a.m. EDT. Residents in both North America and South America will see it, as will Africa, all of Europe, and much of Asia. If the blue moon won't really be blue, then I should be compensated with pumpkin pie. These particles which should be wider than 900 nanometers should be able to affect the scattering of red light in the atmosphere which somehow makes the moon appears blue.
