How this sky is built · forecast illustration, not a camera
Positions follow the time selected below the sky at your chosen location. Back to now restores the current sky. Cloud amount, humidity-based transparency and a seeing proxy come from the forecast; light pollution comes from the 2020 skyglow model. Cloud placement and screen brightness are illustrative, not calibrated images or a satellite map. A marker means above the horizon, not guaranteed visible. Aerosol, smoke, local obstructions and telescope performance are not directly measured here.
Current sky positions update each minute; a selected preview stays at its labelled time. Forecast inputs refresh every five minutes while this page is visible. The headline score and hourly scores describe tonight, separately from the sky explorer.
Use the better hours for bright targets. A darker site helps faint deep sky only if its weather is also better.
