AuroraTonight! is based on an advanced machine learning model that can predict magnetic perturbations around the world up to two hours in advance with unprecedented accuracy. The strongest magnetic perturbations are caused by the aurora, so we can forecast the aurora for any location an hour earlier than the other models.
