City by city

An eclipse of the Moon is the same sight from everywhere the Moon is up. The biggest cities on our list that see all of it, spread round that side of the world, the Moon highest first, then some that see part. Every time is the city’s own clock.

Latitude by latitude

Along each latitude, the longitudes with the Moon above the horizon for the whole time it is in the full shadow, and those with it up at the greatest moment. An eclipse of the Moon looks the same from everywhere it is up.

How we worked it out: the Moon’s and the Sun’s places are Meeus’s solar and lunar theories, the ones the map draws. The Earth’s shadow is sized by Danjon’s rule, as NASA’s catalogue has it, and each contact is the instant the Moon’s edge crosses the shadow’s, found to the second. Each latitude is walked 1° of longitude at a time, the Moon’s altitude asked every 15 minutes. The tests hold these to NASA’s Five Millennium Canon of eclipses: instants within a few minutes, magnitudes within a few thousandths, the phases within two minutes.
