Unlike a solar eclipse, a lunar eclipse is completely safe to watch with the naked eye — no glasses, no filters. Everyone on the night side of Earth sees the same phase at the same moment.

The timeline, minute by minute

Contact times from the published canon (UT1, rounded to the minute) — note the eclipse runs past midnight UT into Dec 21. These instants are the same everywhere on Earth; whether you can see a given phase depends only on whether the Moon is above your horizon — check your city below.

What you'll see

The full Moon slides into Earth's shadow and, during totality, turns a deep copper-red — a blood moon. The colour is real physics: every sunrise and sunset on Earth, refracted through our atmosphere onto the lunar surface at once. With magnitude 1.11895, the Moon travels well inside the umbra. The Moon is 4.4 days after apogee — a slightly smaller moon. It sits in Taurus for the night.

Who sees it — city by city

Computed from the canon contact times and the Moon's real position over each city (geometric altitude; near the horizon, buildings and haze matter). “Maximum” is the local clock time of greatest eclipse. Each city links to its own eclipse page with the full calendar.
