The partial phase starts at 00:46, when a visible dark shadow begins to creep across the lunar surface. Totality begins at 02:10, as the Moon becomes fully immersed in the umbra, often turning a deep red or copper color.The eclipse reaches its peak at 02:18, when the Moon is closest to the center of Earth’s shadow.
