    Solar activity

    ···

    How strongly the Sun is flaring right now. X-ray brightness (GOES satellites) sets a flare’s class: C mild, M medium, X extreme. Below it, the 0–9 Kp index with NOAA’s 3-day forecast. Sources: NOAA SWPC / GOES.

    Orbital regimes

    LIVE

    Turn each orbital shell on or off: Low Earth (LEO), Medium Earth (MEO), Geostationary (GEO), and Molniya. Hiding one doesn’t slow the scene down.

    About the engine

    50,000 satellites, spread across four real orbital shells (LEO, MEO, GEO, Molniya), animated frame-by-frame straight on the graphics card; no game engine or 3D framework underneath, built from scratch in Rust → WebAssembly → WebGPU. It’s a stylised picture of Earth’s orbit, not a live tracker of real satellite positions, but the NASA data streaming around it is genuinely live.

    NOAA scales

    ···

    NOAA’s three warning scales, like storm categories for space weather: radio blackouts (R), solar-radiation storms (S) and geomagnetic storms (G), each with the next-24 h forecast. Source: NOAA SWPC.

    Geomagnetic storm · Dst

    ···

    How deep the current geomagnetic storm goes. The Dst index measures how far a storm has dented Earth’s magnetic field: near 0 nT is quiet, below −50 nT a storm, below −100 nT an intense one. Source: NOAA SWPC / Kyoto.
