The September 7th 2025 total lunar eclipse was one of the darkest observed in modern times. Live visual records consistently described the moon as "brown-gray" or "nearly black," with faint or absent red tones.
This event aligns with historical accounts of rare "black eclipses" that occurred after major atmospheric disturbances. Further atmospheric analysis is highly recommended to identify this rare phenomenon (e.g., aerosol optical depth, …etc.)
