  • Driving in Finland

    We have developed at the FMI a short-range auroral prediction method basing on the real-time monitoring the space weather in South-Finland. If, for example, the spaceweather conditions in the morning exceed certain limit, we can predict that next evening in South-Finland there will be seen auroras with 75 % probability.
