Eclipse Viewer for Any City
Watch the moon swallow the sun — from anywhere on Earth.
🌑 Eclipse sky simulator
This demo approximates the geometry of a pass; a real eclipse viewer (eclipses.bogachev.fr) computes your exact location and time.
Why people love it
Eclipses are rare, awe-inspiring, and always over too fast. This idea bottles that moment: instead of waiting years (and traveling thousands of miles) for the real thing, you can preview any solar eclipse over any city — and see the sky go dark before it happens. For travelers, that turns planning from "hope I'm in the path" into a confident decision: here's exactly how deep the bite gets from Madrid, from Cairo, from Sydney.
People love it because it's a tiny taste of a once-in-a-lifetime event. You feel the geometry — the moon sliding across the sun, the light dimming, the loop of a total eclipse where stars appear in the middle of the day. It's science you can watch instead of read, and it makes the next real eclipse feel personal: you already know what your city will see.
Pick a city and an eclipse above, then drag the coverage slider and hit Play. Full sun, brief darkness — behind your desk, in two minutes. That's the whole appeal.
