Curated dataset · not a live feed · 75 authored moments
The rarest place on Earth
An Earth-observation console. A scan line sweeps the night side of the planet and
ignites a ping for every rare natural coincidence inside its observation window. Open a
ping and you get the physics behind it, the conditions that had to line up, and the odds
of all of them holding at once — decomposed into their factor priors. The windows
are curated scheduling, not observation: nothing here reports what is happening now.
This is a curated catalogue of 75 documented phenomena — aurora
driven to mid-latitudes, milky seas, brinicles, penitentes, catatumbo lightning,
synchronous fireflies, moonbows, sailing stones — each with its position,
observation window, factor decomposition and field notes. It is not a live sensor feed
and never claims to be.
