The eclipse begins with a subtle penumbral phase at 15:21 (GMT-10), which may be hard to detect without instruments. The visible partial phase starts at 16:38, when Earth’s umbra begins to cover a portion of the lunar surface, creating a distinct dark bite on the Moon.At 17:31, the eclipse reaches its peak, with up to 18% of the Moon covered by Earth’s shadow. After this, the shadow gradually recedes, and the partial phase ends at 18:25. The eclipse concludes with the Moon exiting the penumbra at 19:41.
