September 2026 Full Moon: When, Where, and How to See the Harvest Moon

The September 2026 full moon will reach its peak at 12:49 p.m. EDT (1649 GMT) on Sept. 26, when the moon will appear opposite the sun in Earth’s sky.

September’s full moon is commonly known as the Harvest Moon, a traditional designation given to the full moon occurring closest to the September equinox, according to the Old Farmer’s Almanac.

Unfortunately, the Sun, Earth, and Moon will not align for another spectacular lunar eclipse like the one seen in August. Even so, the full moon will offer a striking opportunity for stargazers to observe the lunar disk with the naked eye, through a telescope, or with a camera.

When to See the September Full Moon

Observers across the U.S. will have their first opportunity to see the Harvest Moon as it rises above the eastern horizon at sunset on Sept. 26, appearing among the stars of Pisces.

Near the horizon, the moon will take on a distinctive yellow-orange appearance because its reflected light passes through Earth’s atmosphere, producing an effect known as Rayleigh scattering. The unusual coloration will gradually disappear during the hour after moonrise as the moon moves farther above the horizon.

The lunar disk will also seem especially large while it remains near the horizon because of an optical phenomenon called the “Moon Illusion”. This effect causes our senses to perceive the moon as larger near the horizon than when it is positioned high overhead.

Why It’s Called the Harvest Moon

The September full moon receives the name Harvest Moon when it is the full moon closest to the September equinox. At the equinox, the sun crosses the celestial equator from north to south, signaling the start of astronomical autumn in the northern hemisphere.

The full moon is also sometimes called the Corn Moon, reflecting the period when summer crops were ready to be gathered. According to the Old Farmer’s Almanac, the Native American Anishinaabe people also refer to it as the Turning Leaves Moon.

The Ojibwe Tribe of the Great Lakes region of North America and Canada calls it the Falling Leaves Moon, while the indigenous Assiniboine people named it the Yellow Leaf Moon, referencing the changes that autumn brings to seasonal trees.

September’s full moon occurs alongside China’s Mid-Autumn Festival, a tradition that dates back 3,000 years to the Shang Dynasty. The celebration traditionally brings families together to honor Earth’s natural satellite, with festivities often including moon cakes and illuminated lanterns.

The moon’s appearance also signals the start of the Hindu observance of Pitru Paksha, a period when worshippers honor their ancestors through prayers and food offerings made for deceased family members.

What Else to See in the Sky Around the Full Moon

The Harvest Moon will create a striking scene as it rises in the eastern sky on Sept. 27, but it will not be the only naked-eye astronomical attraction visible in the transitional summer/autumn sky.

Saturn will appear as a bright, star-like object less than 10 degrees below and to the left of the moon roughly an hour after moonrise. With a 6-inch telescope, observers can see the gas giant’s famous rings around its amber-colored disk, along with its brightest moons, Rhea, Tethys, Dione and Titan, appearing in a line extending away from the solar system’s jewel.

The stars forming the Great Square of Pegasus will create a diamond-shaped pattern above and to the left of the moon after sunset. The formation will remain visible even as the intense moonlight surrounding the full moon causes fainter stars to disappear from view.

Those who wake early will have the chance to observe Jupiter and Mars in a striking arrangement, with the two planets appearing on opposite sides of the constellation Cancer, the crab.

Castor and Pollux, representing the heads of the twins depicted by Gemini, will shine above and to the left of Mars. Meanwhile, the colorful stars belonging to Orion and Taurus will sparkle above the southern horizon, offering an early preview of the winter night sky.

Observing Tips

Top Tips to Photograph the Moon

• Use a tripod to keep your camera as stable as possible.
• Use a remote shutter or timer to avoid introducing camera movement.
• A smartphone stargazing app can help identify the precise location of moonrise along your local horizon.
• A lens with a focal length of 12-50 mm works well for landscape photography, while at least 400 mm is recommended for more detailed photographs of the lunar surface.
• The moon can appear especially large when positioned near the horizon alongside foreground objects, while Rayleigh scattering can give it an orange-yellow color. For a cleaner, more “classic” appearance, photograph it after it has climbed high into the sky.

Upcoming Full Moons

These times indicate the precise moment when the moon reaches full illumination. Depending on your location, your local moonrise or moonset can occur several hours before or after these times.
