A rare celestial event is about to captivate stargazers worldwide: the super blue moon. This lunar phenomenon occurs when there are two full moons in a single month, with one occurring very close to the Earth’s closest point to the moon, making it appear larger and brighter than usual. The term “blue” doesn’t refer to the moon’s color but rather its nickname, derived from an old English phrase for a second full moon in a short period. You might be wondering what makes this event so special and how you can witness or even capture it with your camera. In this article, we’ll explore the definition, history, and cultural significance of super blue moons, as well as provide expert tips on observing and photographing this rare occurrence.
What is a Supermoon?
Let’s start with the basics: what exactly makes a supermoon so special, and how does it differ from a regular full moon. A supermoon occurs when the moon is at its closest point to Earth in its elliptical orbit.
Definition and Explanation
A supermoon is a relatively recent term used to describe a full moon that occurs when the moon is at or near its closest point to Earth in its elliptical orbit. This alignment, known as perigee, brings the moon within about 90% of its average distance from our planet. As a result, the moon appears larger and brighter than usual, making it a striking sight for skygazers.
To put this into perspective, consider that a regular full moon can appear up to 14% larger than when it’s at its farthest point, known as apogee. While this difference may seem minor, it can significantly enhance the overall visual impact of the lunar event. For example, during a supermoon, the increased brightness and size of the moon can make it visible for longer periods throughout the night, even in areas with light pollution.
It’s worth noting that supermoons occur when the moon is at its perigee during a full moon phase. This alignment doesn’t happen every month, as there are about two to three full moons each year that meet this criterion. The term “supermoon” was coined by astrologer Richard Nolle in 1979 and has since gained popularity among astronomers and enthusiasts alike.
Types of Supermoons
A supermoon can occur during one of three distinct phases: a perigee moon, an apogee moon, and an eclipse. Perigee moons are when the moon is at its closest point to Earth, resulting in a larger-than-usual appearance in the night sky.
Apogee moons, on the other hand, occur when the moon is at its farthest point from our planet, making it appear smaller than usual. These events can sometimes be overlooked due to their subtle effects on the lunar cycle.
Eclipses, however, have a significant impact on supermoons. During a total lunar eclipse, the Earth’s shadow falls upon the moon, causing it to darken and take on a reddish hue. This rare occurrence is often referred to as a Blood Moon. Super Blue Moons can also be eclipsed, resulting in an even more extraordinary celestial event.
In terms of timing, supermoons can occur within 90 minutes of each other, with the exact alignment depending on various astronomical factors. Understanding these different types of supermoons helps us appreciate the complexities and beauty of our lunar companion’s cycles.

Scientific Explanation of Super Blue Moons
A super blue moon occurs when a full moon coincides with a second full moon within a single month, resulting from lunar orbital patterns. This rare alignment creates unique astronomical phenomena.
Lunar Cycle and Tidal Forces
A super blue moon occurs when a full moon coincides with the moon being at its closest point to Earth, known as perigee, and is also accompanied by a lunar eclipse. This rare alignment of celestial bodies has a profound effect on the tidal forces that shape our oceans.
Tidal forces are the gravitational interactions between the Earth’s oceans and the Moon. When the Moon is at its closest approach to Earth, its gravity pulls more strongly on the ocean waters, causing higher high tides and lower low tides. However, during a full moon, the entire face of the Moon is illuminated by the Sun, making it visible from anywhere on the globe.
The combination of these two factors results in unusually high tidal forces, which can have significant effects on coastal areas and marine ecosystems. For example, the increased tidal range can cause erosion of coastlines, flooding of low-lying areas, and disruption to marine habitats. This unique alignment is what makes a super blue moon so rare and fascinating.
The lunar cycle’s influence on the Earth’s oceans is a crucial aspect of understanding the phenomenon of a super blue moon. The Moon’s elliptical orbit means that its distance from Earth varies throughout the month, affecting the strength of tidal forces.
Why They’re Rare: Understanding the Alignment
A super blue moon requires a precise alignment of celestial bodies, making it an exceptionally rare occurrence. To understand why they’re so rare, let’s break down the necessary conditions. A supermoon occurs when a full moon coincides with the lunar perigee, or the closest point to Earth in its elliptical orbit. However, for a blue moon to occur simultaneously, there must be an additional full moon within the same calendar month.
This requires a specific alignment of the lunar cycle and solar year. The lunar cycle is about 29.5 days, while the solar year is approximately 365.25 days. To have two full moons in one month, the extra day from the leap year has to be factored into the lunar cycle. This happens only when the lunar cycle coincides with a February that has 29 days. The odds are already against us, as this only occurs every 19 years.
The combination of these factors is what makes super blue moons so rare. To put it simply, you need an extra day in February, which happens once every 19 years, and the full moon to coincide with the lunar perigee, all within a single calendar month. This alignment has occurred just three times since 1900: in 1948, 1966, and 2018.
Observation and Photography Tips
To capture the breathtaking beauty of a super blue moon, you’ll want to know how to best observe and photograph this rare celestial event without missing a shot. Here are some expert tips to get you started.
