The year 2020 has brought many surprises and this year’s Halloween is no different.
A rare “blue full moon” will be appearing on Halloween night this year.
While the moon will not look blue, the term “blue moon” is given when two full moons appear in a single month.
A full moon on Halloween occurs roughly once every 19 years – a pattern known as the Metonic Cycle.
The next illuminated Halloween full moon, says astronomers, after 2020 will be in the 2039, 2058, 2077 and 2096.
