How a lunar eclipse unfolds
- Penumbral phase — the Moon enters Earth’s faint outer shadow. It dims only slightly, and most people do not notice.
An eclipse happens at the same instant for everyone who can see the Moon; only the local clock and the Moon’s height differ. It is safe to watch with the naked eye. Weather, hills and buildings are not included in these calculations.
