AURORA BEACON PLUS

The core Aurora Beacon experience remains free.

Aurora Beacon Plus adds deeper Advanced intelligence, Coronal Hole Watch, Solar Events and future outlook alerts.

Aurora forecasting is uncertain by nature. Aurora Beacon is designed to make that uncertainty useful and understandable rather than promise that an aurora will appear.
