IMPORTANT: All forecasts in this app are sample reference data for educational and planning purposes only. Boreal does not connect to any real-time geomagnetic service. Forecasts shown are illustrative examples of how KP index data is presented — they are not live predictions. Always consult official sources such as NOAA Space Weather Prediction Center or the Icelandic Met Office for accurate, up-to-date aurora activity.
