What Is The Blue Supermoon?

The term “Blue Supermoon” refers to a rare and captivating celestial event that combines two separate phenomena: a Blue Moon and a Supermoon. Let’s break down each component to understand what makes this occurrence so unique.

Blue Moon

Contrary to its name, a Blue Moon doesn’t usually appear blue in color. Instead, the term “Blue Moon” refers to the occurrence of an extra full moon within a calendar period. Typically, there are three full moons in a three-month season. However, every once in a while, there’s a fourth full moon in a season. This additional full moon is known as a Blue Moon. The phrase “once in a blue moon” derives from the infrequent nature of this event.


A Supermoon is a term used to describe a full moon that coincides with the moon’s closest approach to Earth in its elliptical orbit. This proximity to our planet makes the moon appear larger and brighter in the sky than a regular full moon. The scientific name for this phenomenon is “perigee-syzygy.”

Now, when a Blue Moon and a Supermoon coincide, we get what’s known as a Blue Supermoon. This event is exceedingly rare, as it requires the alignment of both the lunar cycle and the moon’s orbital cycle. The combination of the Blue Moon and Supermoon creates a dazzling spectacle where the moon appears larger and brighter than usual, while also occurring at a time that doesn’t frequently happen.

The term “blue” in Blue Supermoon doesn’t refer to the moon’s color, but rather to the rarity of the event itself. The moon won’t actually appear blue, unless there’s an unusual atmospheric condition that causes scattering of light, such as from a volcanic eruption or a major wildfire.

The Blue Supermoon is a visual treat for sky enthusiasts, offering a chance to witness a celestial marvel that blends the infrequent presence of an extra full moon with the moon’s closest approach to Earth. It’s an event that invites us to gaze upward in wonder and appreciation of the dynamic dance between Earth, our moon, and the cosmos beyond.

Where Will The Blue Supermoon Be Visible?

The visibility of the Blue Supermoon depends on your geographical location and the specific date of the event. Generally, celestial events like this are visible from a large portion of the Earth, but there might be variations in terms of the moon’s appearance and visibility based on your region.

Here’s some general information:

  • The Blue Supermoon will be visible from most parts of the world where the night sky is visible and weather conditions are clear. This includes regions in North America, South America, Europe, Africa, Asia, and Oceania.
  • However, the exact visibility can vary based on factors such as your latitude, local weather conditions, and light pollution. In areas with less light pollution and clear skies, the Blue Supermoon’s brilliance will be more pronounced and captivating. City lights and atmospheric conditions can sometimes dim the moon’s radiance, but even in such cases, the event is still likely to be visible.
  • To determine the exact timing and visibility of the Blue Supermoon in your specific location, it’s recommended to consult local astronomical resources, stargazing apps, or websites that provide information about celestial events and moonrise/moonset times for your region.

Remember that the Blue Supermoon event occurs only once every couple of decades, so taking the opportunity to observe this rare celestial phenomenon can be a memorable and awe-inspiring experience. The anticipation is palpable as news outlets worldwide buzz with excitement, heralding the arrival of what astronomers project to be the “biggest and brightest moon” of the year.
