Halloween Blue Moon in 2020: A blue moon is rare, but how about when it coincides with Halloween? A blue moon on Halloween looks scarier doesn’t it! Yes folks, a blue moon will be seen in the Halloween night sky on October 31st. A blue moon is a second full moon in a calendar month. The last time such a phenomenon was seen on Halloween was in 1944 and according to NASA the next Halloween Blue Moon will be in 2039! Halloween happens every year, but this year it’s definitely ‘once in a blue moon’.
Even though it’s called a blue moon, the moon doesn’t really look blue. The moon is very rarely blue “because of particles thrown into the atmosphere by natural disasters,” says NASA.
The blue moon on Halloween night will appear near the red planet Mars. If you’re lucky, you might be able to see it if the skies are clear and pollution levels are low.
A blue moon occurs about seven times every 19 years. The blue moon on Halloween is the second full moon after October 1.
2020 has truly been a very special year for sky watchers. This year we had 13 full moons including three super moons, four lunar eclipses, and even a blue moon. The three super moons were seen in March, April and May.
The remaining celestial events of the year will take place on November 30 and December 29. In November we will see the beaver or the freezing moon and a penumbra lunar eclipse and two days before jumping in 2021 we will be watching the cold moon. A full moon in December is called the cold moon because temperatures drop sharply and a beaver moon is the first full moon in November.
