Syracuse,com indicates there will be 13 full moons in 2020, which includes two supermoons (March 9th & April 7th) and a Blue Moon (the Blue Moon will be on Halloween this year).
Per Wikipedia a Supermoon was named by astrologer Richard Noelle in 1979 who described it as:
"A new or full moon which occurs with the Moon at or near (within 90% of) its closest approach to Earth in a given orbit (perigee). In short, Earth, Moon and Sun are all in a line, with Moon in its nearest approach to Earth."
Farmer's Almanac indicates a "Blue Moon" is when there are two full moons in a month, which average every 2 1/2 to 3 years.
