GET /lightpollution
Get an uppskattad Bortle class (1-9) för valfri plats baserad on nearby befolkning density. This is an estimate, not a satellite measurement - it uses weighted befolkning within 100km to approximate sky brightness. Returnerar Bortle class, sky quality rating, uppskattad naked-eye star antal, SQM (Sky Quality Meter) estimate, and aurora viewing suitability. Accurate for stora cities and remote områden; less precise for suburbs. Användbart för astronomy appar, aurora tourism, astrophotography planning, and mörk himmel awareness.
