On August 28, 2026, the Moon will pass through Earth's shadow, creating a deep partial lunar eclipse. At the moment of greatest eclipse, which will occur at 06:13 UTC (02:13 CEST), 96.3% of the lunar disk will be immersed in Earth's umbra. The umbra is the central, darkest region of the shadow, where sunlight is completely blocked.

This event will offer an opportunity for astronomical observation, especially from regions where visibility is optimal, such as Louisiana in the United States. Although it will not be a total eclipse, the high proportion of the lunar surface covered by the umbra will make it a notable spectacle for amateurs and scientists alike.
