Updated October 27, 2026: This article now separates the historic August 2023 Super Blue Moon from real 2026 Moon dates. NASA confirms a monthly Blue Moon on May 31, 2026, and full supermoons on November 24 and December 24, 2026. The 2023 event has already passed; those 2026 dates describe separate Moon events.
Blue Moons and Supermoons in 2026: The Verified Calendar
For 2026, NASA lists a monthly Blue Moon on May 31. Because today is October 27, 2026, that Blue Moon has already occurred. NASA also identifies November 24 and December 24 as full supermoons still ahead this year. A Blue Moon does not automatically qualify as a supermoon, and these 2026 dates should not be confused with the combined Super Blue Moon of August 2023.

In August 2023, skywatchers witnessed a memorable Super Blue Moon. That event combined a monthly Blue Moon with a Supermoon. This article explains the historic event and how it compares with the Moon’s verified 2026 calendar.
What is a Super Blue Moon?
A Super Blue Moon is a rare astronomical phenomenon that intertwines the characteristics of two distinctive lunar events – a Blue Moon and a Supermoon.
To understand the Super Blue Moon, we first need to demystify its components. A Blue Moon is a term used to describe either the third of four full moons in a single season (a seasonal Blue Moon) or, as in our case, the second full moon occurring in a single calendar month (a monthly Blue Moon).
On the other hand, a Supermoon occurs when the full moon coincides with the moon’s closest approach to Earth in its elliptical orbit, known as perigee. This proximity makes the moon appear larger and brighter in our night sky, giving us the phenomenon of a Supermoon.
Therefore, when a full moon event simultaneously fulfills the criteria of being the second full moon of the month (a Blue Moon) and is at its perigee (a Supermoon), we are graced with the spectacle of a Super Blue Moon. This thrilling combination intensifies the rarity and allure of the event, promising a memorable stargazing experience.
A Super Blue Moon is a testament to the universe’s infinite capacity for wonder, serving as a beautiful reminder of our connection to the cosmos.
When Was the Historic 2023 Super Blue Moon?
The historic Super Blue Moon occurred overnight on August 30–31, 2023. It is a past event, not a current viewing forecast. The next section gives the accurate 2026 Moon calendar.
But what sets this Super Blue Moon apart is not just its rarity; it’s also its spectacular display. The 2023 Super Blue Moon was among that year’s closest and brightest full moons, a phenomenon known as a perigee. The Moon passed roughly 222,000 miles from Earth, casting an incandescent glow against the night sky.
To truly appreciate the Super Blue Moon’s splendor, timing is key. Be prepared to watch the sky as the moon ascends at sunset and continues to grace the sky until sunrise. Its glow will be more radiant and its size more apparent during these periods.

The Significance of the Super Blue Moon
A Super Blue Moon is more than just an astronomical event; it’s a symbol of the cosmos’ grandeur and its power to inspire wonder. The phrase “once in a blue moon” is synonymous with rarity, a testament to the infrequency of this event.
While the term “Blue Moon” has nothing to do with the moon’s color (it usually appears its typical gray-white), it holds historical and cultural significance.
The name is steeped in folklore and tradition, with many cultures attributing special meaning to the second full moon in a month.
The “super” aspect of the Super Blue Moon further enhances its awe-inspiring status.
When the moon is at its perigee, or closest point to Earth, it can appear up to 14% larger and 30% brighter in the sky. This results in a more majestic and captivating visual experience, truly living up to the “super” designation.
In essence, the Super Blue Moon serves as a vivid reminder of our place in the cosmos, illuminating the night with its brilliance and casting a spell of enchantment that connects us all under the same celestial canopy.
What is The August Sturgeon Moon?
Before the historic Super Blue Moon appeared, the month of August graces us with another lunar spectacle – the Sturgeon Moon.
In 2023, the Sturgeon Moon reached peak illumination on August 1, serving as a mesmerizing prologue to the awe-inspiring Super Blue Moon later in the month.
The term “Sturgeon Moon” traces back to the Native American tribes of North America. They named each full moon of the year based on the activities or events that occurred during that month.
This name for the first full moon of August has a rich historical origin, revealing a slice of humanity’s relationship with nature.
The first full moon of August was named after the sturgeon, a large fish that was abundantly caught in the Great Lakes and other major bodies of water during this period.
In 2023, the Sturgeon Moon reached peak illumination on August 1, serving as a mesmerizing prologue to the awe-inspiring Super Blue Moon later in the month.
Observing the Sturgeon Moon is akin to embarking on a temporal journey, as it connects us with the age-old traditions and wisdom of our ancestors while simultaneously reminding us of the cyclic rhythms of nature.
How to Watch the Super Blue Moon
The enchantment of observing the Super Blue Moon is an experience unlike any other. However, to fully enjoy this celestial spectacle, certain steps can enhance your viewing experience.
- Location – Find a place away from the city lights, where light pollution is minimal. The darker the surroundings, the more vibrant the moon will appear.
- Timing – The moon will be visible throughout the night, from sunset to sunrise. Its glow will be more radiant and its size more apparent during moonrise and moonset.
- Equipment – A pair of binoculars or a small telescope can enhance your viewing experience, but aren’t necessary. The Super Blue Moon can be enjoyed with the naked eye.
- Patience – Allow your eyes to adjust to the darkness for optimal viewing. This usually takes about 20 minutes.
The Super Blue Moon promises to be a rare and breathtaking spectacle, reminding us all of the vast beauty that the cosmos holds.

Frequently Asked Questions
Q: Is there a blue moon in 2023?
A: Yes. A Super Blue Moon occurred in August 2023. A blue moon refers to the second full moon in a calendar month, which is a relatively rare occurrence.
Q: When to see supermoon August 2023?
A: The August 2023 Super Blue Moon occurred around August 30–31, depending on time zone. Supermoons are best viewed when the moon is closest to the horizon, so try to find a clear viewing spot with little light pollution.
Q: How often do blue moons occur?
A: Blue moons occur approximately once every 2.7 years, hence the phrase “once in a blue moon” to denote a rare event.
Q: What is the rarest moon?
A: One of the rarest lunar events is a “blue moon” – the second full moon in a calendar month. Other rare events include lunar eclipses and supermoons.
Q: When are the remaining 2026 supermoons?
A: NASA lists full supermoons on November 24 and December 24, 2026. Actual appearance depends on viewing conditions; a supermoon appears only modestly larger than an average full moon.
Q: How rare is a blue moon?
A: A blue moon, which is the second full moon in a calendar month, occurs approximately once every 2.7 years.
Q: Why are blue moons so rare?
A: Blue moons are rare because the lunar cycle (the time it takes for the moon to go from new moon to new moon) is approximately 29.5 days, just shy of the typical calendar month.
This means that a full moon usually happens once a month, and only occasionally does a month have two full moons.
Q: What moon happens every 150 years?
A: There is no universal fixed 150-year schedule for a “super blue blood moon“; timing depends on which definition and location you use. This event is a combination of a supermoon (when the moon is at its closest point to Earth), a blue moon (the second full moon in a calendar month), and a blood moon (a total lunar eclipse).
Q: How rare is a Black Moon?
A: A Black Moon, which refers to the second new moon in a calendar month, is a relatively rare occurrence, happening approximately once every 2.5 years.
Q: What is a 0% moon?
A: A 0% moon, also known as a new moon, is when the moon is between the Earth and the Sun, and the side of the moon facing the Earth is in shadow. This means the moon is not visible from Earth.
Q: How many years is 1,000 moons?
A: Given that a lunar month (the time it takes for the moon to go from new moon to new moon) is approximately 29.5 days, 1,000 moons would be roughly 81.3 years.
Q: Does a purple moon exist?
A: A purple moon is not a regularly occurring astronomical event. The color of the moon can appear to change due to atmospheric conditions on Earth, but this is usually a reddish or orange hue, rather than purple.
Q: Why is the Moon 400 times?
A: The moon is approximately 400 times smaller than the sun, but it is also approximately 400 times closer to Earth than the sun. This is why the sun and the moon appear to be the same size in the sky.
Q: Is a moon rainbow rare?
A: A moon rainbow, also known as a lunar rainbow or “moonbow,” is relatively rare because several conditions must be met for it to occur: the moon must be nearly full, the sky must be dark with rain falling opposite the moon, and the sky must be clear between the moon and the rain.
Summary
The August 2023 Super Blue Moon was a real historical skywatching event, not a spectacle that will happen again on the same dates in 2026. Its combination of a Blue Moon and a supermoon made it a memorable subject for skywatchers.
For 2026, remember the distinction: the May 31 Blue Moon has passed, while NASA’s November 24 and December 24 supermoons offer two later viewing opportunities. Check the NASA Moon guide for the current calendar.
