The eclipse begins with the Moon entering the faint penumbral shadow at 04:05 (GMT-10), though this stage is often difficult to notice. The partial phase starts at 05:09, when a visible dark shadow begins to creep across the lunar surface. Totality begins at 06:17, as the Moon becomes fully immersed in the umbra, often turning a deep red or copper color.The eclipse reaches its peak at 06:52, when the Moon is closest to the center of Earth’s shadow. After that, totality ends at 07:29, and the Moon begins to emerge from the umbra. The partial eclipse concludes at 08:39, followed by a gradual fading of the penumbral shadow until the eclipse ends at 04:05.
