Space weather in Finland

Probability of auroras

Probability of auroras estimated from the level of geomagnetic activity:
Blue: no activity
Yellow: medium activity
Red: high activity
Black: no data.

Activity forecast, 1 hour

Geomagnetic activity forecast based on solar wind data. The two values for the next hour give an interval, where RX will be at a 90 % probability. RX is the range of the North component of the geomagnetic field. The colours indicate the level of activity:
low – increased – moderate – high – very high.
