Erhalten Sie current space weather alerts und warnings from NOAA's Space Weather Prediction Center (SWPC). Liefert active geomagnetic storm watches, solar radiation storms, radio blackout alerts, und other space weather advisories. Jeder alert includes severity level, issue time, und description. Unverzichtbar für aurora chasers, satellite operators, aviation planners, und Stromnetz managers who need to monitor geomagnetic disturbances.

Erhalten Sie recent planetary K-index (Kp) values from NOAA SWPC, the primary indicator of geomagnetic storm activity. The Kp index ranges from 0 (quiet) to 9 (extreme storm). Werte of 5+ indicate geomagnetic storms visible as aurora at lower latitudes. Liefert eine time series of recent Kp readings. Entscheidend für aurora prediction apps, satellite drag calculations, GPS accuracy monitoring, und space weather dashboards.

Erhalten Sie recent solar flare events from NOAA SWPC, einschließlich flare class (A, B, C, M, X), peak time, begin/end times, und source active region. M-class und X-class flares can cause radio blackouts, GPS disruptions, und enhanced aurora displays. Nützlich für amateur radio operators monitoring propagation conditions, aurora forecasters, space weather researchers, und satellite operators assessing radiation risk.

Erhalten Sie recent daily sunspot numbers from NOAA SWPC, tracking solar activity levels. Sunspot numbers correlate with the 11-year solar cycle und predict space weather intensity. Höhere sunspot counts mean more frequent solar flares, coronal mass ejections, und aurora displays. Nützlich für solar cycle tracking dashboards, long-term space Wettervorhersageing, amateur astronomy tools, und climate research applications studying solar irradiance variability.

Erhalten Sie ein 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. Liefert Bortle class, sky quality rating, estimated naked-eye star count, SQM (Sky Quality Meter) estimate, und aurora viewing suitability. Accurate for major cities und remote areas; less precise for suburbs. Nützlich für astronomy apps, aurora tourism, astrophotography planning, und dark sky awareness.

Erhalten Sie ein aurora borealis viewing score for any location, combining Echtzeit space Wetterdaten (Kp index, solar wind) with local Wetterbedingungen (cloud cover, light pollution) und geographic latitude. Liefert eine composite score from 0-100 indicating how likely you are to see the Northern Lights tonight. Ideal für aurora alert apps, tourism platforms in Nordic regions, photography planning tools, und travel apps that help visitors time their trips to see the aurora.
