Deep Partial Lunar Eclipse Creates Near-Total ‘Blood Moon’ Effect Across the Americas
On August 28, 2026, skywatchers across North and South America, as well as parts of western Europe and Africa, observed a deep partial lunar eclipse that coincided with the August Sturgeon Full Moon. According to data from NASA’s Scientific Visualization Studio, the event reached its maximum peak at 4:13 a.m. UTC (9:43 a.m. IST), when Earth’s dark umbral shadow covered approximately 96.3% of the lunar surface. Although the celestial alignment fell just short of a total eclipse, the near-complete coverage left only a sliver of the Moon illuminated, creating a striking visual effect closely resembling a “Blood Moon”. Stage-by-stage timings, eclipse maps, and shadow trajectories were detailed in NASA’s Scientific Visualization Studio feature on the August 27–28, 2026 deep partial lunar eclipse, as well as in the Times of India’s coverage of the 2026 partial lunar eclipse.
The distinctive rusty-red and coppery coloration observed across the shadowed portion of the disk was caused by sunlight filtering through Earth’s atmosphere. Through a process known as Rayleigh scattering, shorter blue wavelengths of light scatter away, while longer red and orange wavelengths bend inward around the planet and project directly onto the lunar terrain. NASA scientists aptly described this optical phenomenon as projecting the collective hues of all the world’s simultaneous sunrises and sunsets onto the Moon. Further breakdown of the underlying atmospheric physics can be explored in the Indian Express’ report on NASA’s lunar-eclipse insights, while regional viewing conditions and photo galleries were featured in Folha de S.Paulo’s August 28 coverage from Brazil.
Visibility of the event varied significantly depending on geographic location. The Americas served as the primary observation corridor for the entire sequence, which began with the partial phase at 2:34 a.m. UTC and concluded at 5:52 a.m. UTC. Observers in western Europe and Africa caught the earlier stages before moonset, whereas skywatchers in India and South Asia missed out entirely because the peak occurred during daylight hours when the Moon was below the horizon. Despite missing full totality, the extraordinary 96.3% umbral depth made the alignment one of the most dramatic partial lunar eclipses in recent years.
