The difference between a super moon and a regular full moon is distance: a super moon occurs when the full moon coincides with perigee—its closest approach to Earth—making it appear about 14% larger and 30% brighter than a regular full moon at apogee. The term “super moon” was coined in 1979 by astrologer Richard Nolle, but the phenomenon itself has been observed and recorded for millennia by Babylonian, Greek, Chinese, and medieval European astronomers.
What Exactly Defines a Super Moon?
The moon’s orbit around Earth is not a perfect circle. It is an ellipse, meaning the distance between the two bodies varies by roughly 50,000 kilometers over the course of a month. When the moon reaches the point closest to Earth, that is perigee. When it is farthest, that is apogee. A super moon is a full moon that coincides with perigee, or comes within 90% of it.
Richard Nolle defined it as “a new or full moon which occurs with the moon at or near (within 90% of) its closest approach to Earth in a given orbit.” Astronomers prefer the term perigee-syzygy (syzygy meaning the alignment of Earth, moon, and sun). The popular definition settled on full moons within 90% of perigee, which gives us three to four super moons per year.
A regular full moon at apogee is sometimes called a micro moon. It appears smaller and dimmer. The difference between a super moon and a micro moon is stark: the super moon’s disk is roughly the size of a dinner plate held at arm’s length, while the micro moon is closer to a saucer.
Where Did the Super Moon Concept Come From?
Before Nolle’s 1979 coinage, the phenomenon had no separate name. Ancient observers saw it, recorded it, and treated it differently.
The Babylonian astronomers of the 7th century BCE tracked lunar perigee in their cuneiform tablets (the Enuma Anu Enlil series). They noted that eclipses occurring near perigee produced longer totality, and they associated these with the reigns of kings. A super moon eclipse was a royal omen, not a popular one.
The Greek astronomer Hipparchus (c. 150 BCE) calculated the moon’s distance using parallax during a solar eclipse near perigee. He knew the moon was closer. He did not give it a special name.
In medieval European astrology, the moon at perigee was called the moon in her perigee or Luna in perigaeo. Astrological texts from the 12th century, such as those of Abraham ibn Ezra, warned that the moon at perigee amplified her influence on tides, humors, and human temperaments. A full moon at perigee was considered dangerously potent for bloodletting and surgery.
The Chinese imperial astronomers of the Tang dynasty (618-907 CE) recorded super moons as “great bright moons” (da ming yue) and correlated them with floods and political unrest. The Jiu Tang Shu (Old Book of Tang) contains a record from 724 CE describing a moon so bright that “the stars were hidden for three nights.”
What Does a Super Moon Mean Symbolically?
In occult and esoteric traditions, the super moon amplifies everything the full moon already governs. The full moon is the point of revelation, harvest, and culmination. The super moon is that point sharpened to a blade.
The symbolic logic is simple: the moon’s influence is tied to its proximity. In Hermetic astrology, the moon rules the tides of the body (blood, lymph, menstrual cycle) and the tides of the soul (emotion, intuition, memory). A closer moon means stronger pull. The Emerald Tablet does not mention the moon directly, but the principle of “as above, so below” applies: the closer the celestial body, the more direct its influence on the sublunar realm.
In Western ceremonial magic, the super moon is treated as a time of heightened visibility. Spirits are said to be more easily seen, dreams more vivid, and boundaries between worlds thinner. The Key of Solomon (14th century) specifies that operations for summoning spirits should be performed when the moon is “increasing in light and in her perigee.” The grimoire does not use the term super moon, but the instruction is the same.
In Hellenistic folk magic, the super moon was called selene megiste (great moon). Magical papyri from Roman Egypt (the Greek Magical Papyri, PGM) include spells to be performed “when the moon is full and in her closest station.” One spell for dream divination (PGM IV. 2622-2707) specifies that the practitioner must lie facing the moon at midnight during this configuration.
The Wiccan tradition, which emerged in the mid-20th century, adopted the super moon as a special esbat (full moon ritual). Gerald Gardner’s Book of Shadows (1949) does not mention super moons by name, but later Wiccan authors such as Doreen Valiente (1950s) described the “closest moon” as a time for high magic rather than routine circle work.
How Do Practitioners Work with a Super Moon?
The super moon is not a time for subtle work. It is a time for work that demands force.
Charging tools and talismans is the most common practice. The super moon’s light is considered denser, more saturated with lunar energy. A wand, crystal, or mirror left in direct moonlight during a super moon is said to hold that charge for the full lunar month. Practitioners in the Hoodoo and conjure tradition often set out bottles of water or oil under the super moon, sealing them at the exact moment of fullness. The water is used later for washes, baths, and anointing.
Dream work intensifies. The super moon’s brightness can disrupt sleep, but practitioners use this. A dream pillow stuffed with mugwort and lavender, placed under the pillow on the night of the super moon, is said to produce prophetic dreams. The Greek Magical Papyri recommend sleeping on a bed of laurel leaves during the great moon to receive visions from Hekate.
Divination during a super moon is treated as more accurate but more dangerous. Tarot readings, scrying, and pendulum work are said to cut through deception more easily, but the practitioner must ground afterward. The energy is not gentle. Some traditions advise against reading for others during a super moon, as the reader’s own emotions are amplified and can contaminate the interpretation.
Banishing and releasing are also common. The super moon’s brightness exposes what is hidden. Practitioners write what they wish to release on paper, read it aloud under the moon, and burn it. The ash is buried or scattered. The logic: what the super moon reveals, it can also carry away.
How Does a Super Moon Compare to a Lunar Eclipse?
A lunar eclipse occurs when the Earth passes between the sun and the moon, casting its shadow on the lunar surface. A super moon lunar eclipse is rare and powerful. For a full breakdown of this phenomenon, see our guide to the eclipses hub.
The difference is one of mechanism. A super moon is about distance. A lunar eclipse is about alignment. They can coincide: a super moon that passes through Earth’s shadow becomes a super moon eclipse. The last one occurred in May 2021, and the next will be in 2029.
In occult terms, the eclipse is considered a disruption of the lunar current. The moon is “eaten” by the shadow, and the energy is chaotic. The super moon amplifies that chaos. Practitioners who work with eclipses treat them as times of transformation rather than manifestation. The super moon eclipse is the most intense version of that: a door that opens and closes in the same night.
A regular super moon is safer for practical magic. The eclipse carries a quality of dissolution that many traditions avoid.
What Do People Get Wrong About Super Moons?
The most common misconception is that super moons cause natural disasters. This idea circulates every time a super moon appears. The claim: because the moon’s gravity is stronger at perigee, it will trigger earthquakes, volcanic eruptions, and extreme tides.
The evidence does not support this. The moon’s gravitational pull at perigee is about 42% stronger than at apogee. But that difference is small compared to the sun’s gravitational influence. The US Geological Survey has found no correlation between super moons and seismic activity. The 2011 Tohoku earthquake and tsunami were sometimes blamed on the super moon that occurred two weeks earlier. The earthquake was caused by tectonic stress that had been building for centuries. The moon had nothing to do with it.
Another misconception: that the super moon is a rare event. It is not. A super moon occurs three to four times per year. The term’s popularity surged after 2011, when a particularly close super moon (the 2011 super moon on March 19) received heavy media coverage. People began treating it as a once-in-a-lifetime event. It is not.
A third misconception: that the super moon is visibly enormous to the naked eye. The 14% size difference is real but subtle. The famous “moon illusion” (the moon appearing larger near the horizon) is a psychological effect, not an astronomical one. A super moon at zenith looks only slightly larger than a regular full moon. The dramatic photos online are composites or long-lens shots.
FAQ
How often do super moons occur? Three to four times per year, in consecutive months, because the lunar cycle and the perigee cycle are roughly 27 days each.
Can you see a super moon during the day? Yes. A super moon rises at sunset and sets at sunrise, so it is visible all night. During the day it is below the horizon.
Is a super moon more dangerous for magic? Not dangerous, but more intense. Practitioners who are sensitive to lunar energy may find it overwhelming. Grounding and shielding are recommended.
Does a super moon affect human behavior? Studies show no consistent effect on crime, hospital admissions, or psychiatric episodes. The belief is cultural, not scientific.
Closing
The super moon is not a different moon. It is the same moon, closer. That proximity changes how we work with it, how we see it, and what we ask of it. For the practitioner, the super moon is a reminder that distance matters. The closer the source, the stronger the current.
