Explanation:
The last full moon was doubly unusual.
First of all, it was a
blue moon.
A modern definition of a
blue
moon is a second full moon to occur during one
calendar month.
Since there are 13 full moons in 2023, one month has to have two -- and that month
was August.
The first full moon was on August 1 and named a
Sturgeon Moon.
The second reason that the last full moon was
unusual was because it was a
supermoon.
A modern definition of
supermoon is a moon that reaches its full
phase when it is relatively close to Earth -- and so
appears
a bit larger and brighter than average.
Pictured, the
blue supermoon of 2023
was imaged
hovering far behind a historic
castle and
lighthouse in
Syracuse,
Sicily,
Italy.
