The eclipse begins with a subtle penumbral phase at 17:12 (GMT-9), which may be hard to detect without instruments. The visible partial phase starts at 18:28, when Earth’s umbra begins to cover a portion of the lunar surface, creating a distinct dark bite on the Moon.At 19:56, the eclipse reaches its peak, with up to 70% of the Moon covered by Earth’s shadow.
