How It Works
1. Pick a date at least 8 days ahead when you think a G3 geomagnetic storm (Kp ≥ 7) will occur.
2. Flarient automatically checks every 30 minutes. When a G3 storm is detected, the closest prediction wins.
3. The winner receives 12 months of Flarient Premium (£48 value), awarded automatically.
4. All other pending predictions are marked as lost and a new round begins.
5. Your forecast accuracy score is tracked on your Event Passport — the better your predictions, the higher your reputation.
