August’s Lunar Marvels: Prepare for Two Supermoons and a Captivating Blue Moon in 2023!

In the month of August 2023, stargazers will witness a remarkable astronomical event featuring not one, but two supermoons along with the appearance of an elusive blue moon. Supermoons occur when the full moon’s orbit brings it closest to Earth, resulting in a slightly larger and brighter appearance. This year’s supermoon cycle is exceptionally special, as there will be four consecutive occurrences, starting in July and culminating in September. Let’s delve deeper into the fascinating details of these celestial phenomena.

The Supermoon Phenomenon:

A supermoon occurs when the full moon aligns with its closest approach to Earth, known as the perigee. This happens because the moon’s orbit around Earth is not perfectly circular but rather elliptical in shape. During the perigee stage, the moon is approximately 226,000 miles away from our planet, making it appear larger and brighter when observed from Earth compared to a regular full moon.

The Blue Moon Enigma:

Contrary to popular belief, a blue moon does not refer to the moon’s color; rather, it denotes the second full moon that occurs within a single calendar month. Since a full moon typically appears every 29 days, there’s a chance for two full moons to fall within the same month, resulting in a blue moon. These occurrences are relatively infrequent, happening roughly every two and a half years.

The Sturgeon Moon – First Supermoon of August:

On Tuesday, August 1, the first of August’s supermoons, also known as the Sturgeon Moon, will peak at 2:32 p.m. The name “Sturgeon Moon” originated from Native American groups, particularly those in the Great Lakes region, who noticed abundant sturgeon catches during this month. Different cultures have various names for the August full moon, including the “Grain Moon” for the Algonquins, the “Green Corn Moon,” the “Barley Moon,” or the “Fruit Moon,” reflecting the harvest season.

The Second Supermoon – A Rare Blue Moon


August will end with a grand celestial finale, featuring a blue moon on Wednesday, August 30, reaching its peak at 9:36 p.m. This blue moon is special not only for being the second full moon of the month but also classified as a supermoon. It will be the closest full moon to Earth for the entire year, adding an extra layer of astronomical intrigue. 

Observing the Celestial Spectacle:

Astronomy enthusiasts planning to witness these lunar events should find a location away from city lights for the clearest view. Using a telescope or binoculars can enhance the experience. For supermoons, it’s best to look for a location with an unobstructed view of the horizon, as they rise at sunset.

Understanding Supermoon Causes:

Supermoons result from the unique alignment of the Earth, moon, and sun. The moon’s elliptical orbit causes its distance from Earth to change throughout the month. When the full moon coincides with the moon’s closest approach to Earth (perigee), a supermoon occurs, creating a visually spectacular display.

History and Cultural Significance:

The term “supermoon” has its roots in astrology, but astronomers use the term “perigee-syzygy” to describe this celestial alignment. Supermoons hold cultural significance in various indigenous cultures and are subjects of folklore and mythology. They also draw large numbers of spectators for night-time photography and observation due to their increased brightness and size.

The Blue Moon’s Origin and Calculation


The term “Blue Moon” dates back centuries, initially symbolizing absurdity and improbability. The most widely accepted definition refers to the second full moon within a calendar month. Blue Moons are a result of the incongruity between our calendar system and the lunar cycle.

Frequency and Cultural Significance of Blue Moons:

Blue Moons occur, on average, once every 2.5 to 3 years based on the common definition. They hold cultural significance, symbolizing rare events or occurrences. From a scientific standpoint, Blue Moons offer an opportunity for lunar observation and appreciation for our natural world’s rhythms. 


August 2023 promises to be a magnificent time for astronomers and stargazers, with two supermoons and a rare blue moon gracing our skies. These celestial events offer a unique opportunity to marvel at the wonders of the cosmos and connect with the timeless allure of the moon and its dance around our planet.
