A "Super Blue Moon" is a term used to describe a rare lunar event that combines three characteristics: a supermoon, a blue moon, and a total lunar eclipse.
Supermoon: A supermoon occurs when a full moon coincides with the moon's closest approach to Earth in its elliptical orbit, known as the perigee. This makes the moon appear slightly larger and brighter than usual.
Blue Moon: The term "blue moon" traditionally refers to the second full moon within a calendar month. It is called a "blue moon" because it is relatively rare for two full moons to occur within the same month.
Total Lunar Eclipse: A total lunar eclipse happens when the Earth passes between the Sun and the Moon, casting a shadow on the Moon. During a total lunar eclipse, the Moon may appear reddish or coppery in color, often referred to as a "blood moon."
In 2023, there is no occurrence of a Super Blue Moon that includes all three characteristics mentioned above. However, individual events such as supermoons, blue moons, and lunar eclipses may occur separately throughout the year. To observe specific dates for these events, it is advisable to consult a reliable astronomical calendar or website closer to the desired time.
