1973 Supermoons

In 1973 there were three supermoons: January 18, November 10, and December 9.

A full supermoon is a full moon that nearly coincides with the closest that the Moon comes to the Earth in its orbit, called perigee. The moon has a larger-than-usual appearance when you look at it. There isn’t an official definition for how close the moon needs to be to the earth to be considered a supermoon.

Was there a blue moon in 1973?

No, there was not a blue moon in 1973 as each month had one full moon and each season had three full moons.

There are two definitions of blue moons. The most common, and the one you likely know, is when two full moons occur in the same month. The second full moon is typically called a blue moon.

The second definition of a blue moon relates to having an extra full moon during a season. When a season has four full moons, the third full moon of the season is also called a blue moon or a seasonal blue moon to help distinguish between the other definition.
