GET /lightpollution

Saage an estimated Bortle class (1-9) for any location based on nearby population density. This is an estimate, not a satellite measurement - it uses weighted population within 100km to approximate sky brightness. Tagastab Bortle class, sky quality rating, estimated naked-eye star count, SQM (Sky Quality Meter) estimate, and aurora viewing suitability. Accurate for major cities and remote areas; less precise for suburbs. Kasulik astronomy apps, aurora tourism, astrophotography planning, and dark sky awareness.
