The eclipse begins with the Moon entering the faint penumbral shadow at 00:53 (GMT-10), though this stage is often difficult to notice. The partial phase starts at 01:49, when a visible dark shadow begins to creep across the lunar surface. Totality begins at 02:52, as the Moon becomes fully immersed in the umbra, often turning a deep red or copper color.The eclipse reaches its peak at 03:32, when the Moon is closest to the center of Earth’s shadow. After that, totality ends at 04:09, and the Moon begins to emerge from the umbra. The partial eclipse concludes at 05:13, followed by a gradual fading of the penumbral shadow until the eclipse ends at 00:53.
