A partial lunar eclipse on Aug. 27-28, 2026, will see Earth’s shadow cover 96% of the moon, with the event visible globally and safe to observe without special equipment. The eclipse, part of a two-part celestial show following a solar eclipse in mid-August, will feature five distinct stages, including a reddish hue during the peak phase, as sunlight refracts through Earth’s atmosphere.
Five Stages of the Partial Lunar Eclipse
The Aug. 27-28 partial lunar eclipse will unfold in five stages, each marked by the moon’s progression through Earth’s shadow. The event begins at 9:23 p.m. EDT on Aug. 27 (0123 GMT on Aug. 28) with the penumbral stage, when Earth’s outer shadow starts darkening the moon’s surface according to TimeandDate.com. This phase is subtle, with the moon’s dimming most noticeable just before the inner umbra begins to take effect.
The partial phase starts at 10:33 p.m. EDT (0233 GMT) as Earth’s inner umbra bites into the moon’s southwestern edge, creating a shadow that spreads rapidly. This stage offers a rare view of Earth’s silhouette against the lunar surface, with the umbra’s distinct curve visible to observers per the first source. The eclipse reaches its peak at 12:12 a.m. EDT (0412 GMT) on Aug. 28, when 96% of the moon is cloaked in shadow, casting a reddish-orange hue due to sunlight refracting through Earth’s atmosphere as explained by Space.
What to expect from each stage of the partial
The moon’s exposure to direct sunlight increases as Earth’s shadow recedes, with the inner umbra fully departing at 1:51 a.m. EDT (0551 GMT) on Aug. 28. The event concludes when the outer penumbral shadow vanishes at 3:01 a.m. EDT (0701 GMT), marking the end of the eclipse per the first source. The next similar eclipse will occur on New Year’s Eve 2028, according to livescience.com.
Viewing and Photography Tips
Unlike solar eclipses, the Aug. 27-28 lunar eclipse is safe to observe with the naked eye or simple equipment. livescience.com recommends binoculars, telescopes, or cameras for enhanced views, with specific gear suggestions for optimal photography. The site highlights that smartphones can capture wide-angle shots of the eclipsed moon against landscapes, though detailed close-ups require telephoto lenses or telescopes.
Photographers should adjust camera settings as the moon darkens, starting with ISO 100, f/8-f/11, and 1/100-1/125-second exposures before lengthening shutter speeds. Shooting in RAW format and using exposure bracketing will provide flexibility in post-processing per the second source. A sturdy tripod is essential as the moon’s brightness decreases during the eclipse.
The site also recommends the StarSense Explorer LT 70AZ telescope, the Seestar S30 Pro smart telescope, and Sony’s high-resolution mirrorless camera for capturing the event. A lightweight telephoto zoom lens is ideal for photographers traveling for an eclipse, according to the second source. Essential accessories include a sturdy tripod, as noted in the first source.
How to see and photograph the partial lunar eclipse
The event will be most visible in North and South America, where the moon will appear high in the night sky. In Europe, observers will see the eclipse before dawn as the moon sets according to livescience.com. No solar filters or eye protection are required, as the moon’s light during the eclipse is not harmful to human vision. No solar filters or special eye protection are ever required,
the FAQ section states.
Why This Eclipse Matters
This eclipse is the deepest partial lunar eclipse until the next total lunar eclipse on Dec. 31, 2028, making it a rare opportunity for stargazers. The event’s name, “Sturgeon Moon,” references the large lake sturgeon of the Great Lakes and Lake Champlain, which were historically abundant in summer as noted by Space. The reddish hue during the eclipse, caused by sunlight scattering through Earth’s atmosphere, offers a vivid reminder of the planet’s role in shaping celestial phenomena.
For amateur astronomers and casual observers alike, the eclipse underscores the accessibility of astronomy.
The eclipse’s visibility across North and South America, combined with its unique red hue and historical name, makes it a significant event for both scientific observation and public engagement. With the moon’s surface appearing coppery red to cameras
and the opportunity to witness Earth’s shadow in real time, the Aug. 27-28 eclipse promises to be a memorable celestial spectacle.
