Information and data sources

This website is created by aurora enthusiasts for aurora enthusiasts. The information you find here is based on open data and our own analyses, providing an indication of when the aurora might be visible.

We gather real-time measurements from satellites and instruments that monitor space weather, including the NOAA Space Weather Prediction Center (SWPC). This provides us with information about solar wind, Bz direction, and the Kp index, all of which are key factors in predicting when the aurora might appear. Additionally, we use models and algorithms to assess when conditions are optimal for viewing the aurora from the ground.

Our goal is to make the information as easy to understand as possible, so you can use it to plan your observations. All data interpretation is done by us at nordlysvarsel.com. We want to emphasize that our assessments are not official statements but are based on open sources and our own analyses.

⚠️ The information found on this page should not be used for critical decisions or situations where accuracy is crucial.
