Overview
- A very deep partial lunar eclipse will occur on Aug. 27–28, 2026 and place most of the Moon inside Earth’s umbra so only a thin sunlit crescent remains.
- Technical forecasts put the umbral magnitude at about 0.9299, which means roughly 93% of the Moon’s diameter is shadowed even though area-based figures are commonly reported near 96%.
- The eclipse will be visible across much of North and South America and parts of Europe and Africa, with Space.com estimating about 3.3 billion people live in regions where the Moon can be seen during the event.
- Observers can watch the coppery or red tint produced by sunlight refracted through Earth’s atmosphere with the naked eye, and binoculars or a small telescope will show more lunar detail.
- Multiple observatories and projects including Griffith Observatory, The Virtual Telescope Project, and Timeanddate.com will offer free livestreams and commentary to reach viewers affected by clouds or city light pollution.
