August’s full sturgeon moon will share the night sky with a dramatic partial lunar eclipse, as Earth’s shadow covers nearly the entire visible surface of the Moon. The celestial event will offer sky-watchers across much of the Americas an impressive opportunity to observe the changing lunar landscape.
The end of August will bring more than an ordinary full moon. The annual sturgeon moon will coincide with a major partial lunar eclipse, creating one of the most striking astronomical displays of the month. Although the event will technically be classified as a partial eclipse, the Moon will come remarkably close to total coverage, with approximately 96% of its bright, visible surface passing into Earth’s darkest shadow.
For astronomy enthusiasts alongside casual stargazers who delight in gazing upward after dark, this occasion offers a readily available chance to observe how the Sun, Earth, and Moon interact. Extensive regions across North and South America are anticipated to enjoy the opportunity to view the entirety or a significant portion of the eclipse, contingent upon regional weather patterns and atmospheric clarity.
How the partial lunar eclipse will happen
A lunar eclipse occurs when the Earth moves directly between the Sun and the Moon. In this position, the planet blocks sunlight that would normally illuminate the lunar surface and casts its shadow across the Moon.
The darkest central portion of Earth’s shadow is known as the umbra. When the entire Moon passes through this region, observers witness a total lunar eclipse. If only part of the Moon enters the umbra while another section remains outside it, the event is classified as a partial lunar eclipse.
That is what will happen during the August event. However, this particular eclipse will be unusually extensive because Earth’s shadow will cover about 96% of the Moon’s illuminated surface. As a result, the visual difference between this event and a total eclipse may appear relatively small to some observers.
Lunar eclipses can only take place during a full moon since the Earth needs to be located right between the Sun and its natural satellite. Even so, a lunar eclipse does not happen every single month. The orbit of the Moon is inclined relative to Earth’s trajectory around the Sun, meaning that the three celestial bodies fail to reach the required alignment during each full moon.
The eclipse is forecasted to commence late Thursday night, attaining its peak shortly past midnight within the Eastern Time zone. The exact instant the Moon looks most luminous will occur just moments afterward, bringing the two celestial phenomena virtually together.
For observers in favorable locations across the Americas, the nighttime timing should make the phenomenon easier to follow as Earth’s shadow gradually moves across the lunar surface.
Will the Moon turn red or orange?
One of the most recognizable features of a lunar eclipse is the possibility that the Moon may take on reddish or orange tones.
During a total lunar eclipse, the Moon can sometimes appear deep red, copper-colored or orange. This phenomenon is often referred to as a “blood moon,” although the name is a popular description rather than a scientific term.
The color transformation stems from Earth’s atmosphere. When sunlight passes along the planet’s periphery, the shorter wavelengths linked to violet and blue hues get dispersed much more readily. Conversely, the extended wavelengths—encompassing orange and red illumination—tend to press on through the atmospheric layer and ultimately strike the Moon.
Because this event will be a near-total partial eclipse rather than a complete one, its exact appearance will be difficult to predict in advance.
The portion of the Moon deepest within Earth’s shadow could become noticeably darker and may develop reddish tones, particularly in areas farthest from the remaining illuminated section. Atmospheric conditions can influence how intense those colors become.
This uncertainty is part of what makes lunar eclipses visually interesting. No two events appear exactly the same, and the Moon’s colors can vary according to conditions in Earth’s atmosphere.
The night could potentially offer additional astronomical interest as geomagnetic activity may also create conditions favorable for auroras in parts of the northern United States. Although auroras and lunar eclipses are separate phenomena, the possibility of both occurring during the same period could make the night particularly memorable for sky-watchers in certain regions.
How common are lunar eclipses?
Lunar eclipses are not exceptionally rare, but they do not occur with the same frequency every year.
The number of lunar eclipses varies depending on the orbital alignment of the Earth, Moon and Sun. Many years offer two opportunities to observe a lunar eclipse, while some years can include three. In other cases, the number of visible eclipses from particular locations may be more limited.
Earlier in 2026, another lunar eclipse occurred in March. That event was a total lunar eclipse, with some of the best viewing conditions occurring across Australia and parts of the Pacific region.
Each eclipse is different. Some are total, while others are partial or penumbral. Their duration, appearance and visibility also depend on the location of the observer and the exact geometry of the celestial alignment.
The August eclipse will stand out because of the large percentage of the Moon that will enter Earth’s umbra. With roughly 96% of the visible lunar surface affected, it will rank as a particularly dramatic example of a partial lunar eclipse.
How to watch the lunar eclipse
One of the benefits of a lunar eclipse is that it can be watched safely without the need for specialized protective gear.
Unlike a solar eclipse, which demands adequate eye protection while observing the Sun, a lunar eclipse can be viewed safely with the naked eye. No specialized glasses or filters are required.
Still, choosing the right location can significantly improve the experience.
Bright streetlights, buildings and other sources of artificial illumination can make it more difficult to appreciate the details of the night sky. An open area away from strong city lights is generally the best choice.
A nearby park, a quiet open field or another location with an unobstructed view of the sky can provide better conditions. It is also useful to avoid places where tall buildings or trees may block the Moon.
Binoculars are not required, but they can make the gradual movement of Earth’s shadow easier to observe. A telescope can reveal additional details on the lunar surface, although the eclipse itself will remain clearly visible without any equipment.
Atmospheric conditions will ultimately dictate the experience. Even across zones where the eclipse remains completely unobstructed, cloud cover might prevent spectators from viewing the Moon. Reviewing the local forecast prior to stepping outside can help pinpoint optimal viewing conditions.
The gathering furthermore delivers a chance to simply take in the sky. The metamorphosis is going to unfold little by little, enabling spectators to track the evolving look of the Moon instead of just catching a fleeting instant.
Why August’s full moon is called the sturgeon moon
The full moon in August is widely known as the sturgeon moon, a name connected to Indigenous traditions in North America.
The designation is particularly associated with Algonquin-speaking peoples and other Native American communities living near the Great Lakes. During this period of the year, lake sturgeon were historically abundant and represented an important food source.
Like many traditional names for full moons, the term reflects seasonal changes and the relationship between communities and the natural environment.
However, the sturgeon moon is not the only name used for August’s full moon. Different Indigenous communities developed their own names based on the plants, animals and seasonal events that were most important in their regions.
Some Indigenous groups associated the August moon with black cherries, while others connected it to the period when green corn was growing or being harvested.
These designations serve as a reminder that the Moon has historically functioned as more than merely an object for scientific study. For ages, lunar phases remained closely tied to seasonal customs, sustenance sources, and the cadences of daily existence.
More full moons to come in 2026
The astronomical calendar will continue to offer several full moons after the August sturgeon moon.
September will bring the harvest moon, followed by October’s hunter’s moon. November will feature the beaver moon, while December’s full moon is traditionally known as the cold moon.
The final months of the year will also bring additional interest because the full moons in November and December are expected to occur under conditions associated with supermoons.
A supermoon takes place when a full moon occurs while the Moon is near one of the closest points to Earth in its elliptical orbit. From the ground, the Moon may appear somewhat larger and brighter than usual.
Although the difference may not always be obvious without comparison, supermoons remain among the most popular celestial events for photographers and sky-watchers.
The upcoming lunar eclipse in August will still stand out as one of the most remarkable chances to gaze at the Moon throughout the year. The pairing of a full sturgeon moon with a partial eclipse obscuring nearly the entire lunar disk is set to turn a standard evening into a clear showcase of the orbital mechanics governing Earth, the Moon, and the Sun.
For individuals residing in regions with favorable visibility, simply having an unobstructed sky and a clear upward vantage point is all that is required. As the shadow of Earth gradually creeps across the lunar surface, onlookers get to witness a cosmic alignment that highlights the extraordinary accuracy of our solar system.
Because no specialized gear is necessary, this nearly total partial lunar eclipse will be within reach for anyone who steps outside to gaze at the evening sky. Whether observed with binoculars, a telescope, or merely the unaided eye, the occasion serves as a reminder that some of the most breathtaking celestial events can be witnessed straight from Earth.
