The eclipse begins with a subtle penumbral phase at 16:20 (GMT-9), which may be hard to detect without instruments. The visible partial phase starts at 17:33, when Earth’s umbra begins to cover a portion of the lunar surface, creating a distinct dark bite on the Moon.At 19:10, the eclipse reaches its peak, with up to 85% of the Moon covered by Earth’s shadow. After this, the shadow gradually recedes, and the partial phase ends at 20:47. The eclipse concludes with the Moon exiting the penumbra at 22:00.
