.20 satellites containing world class instruments from the University of Oslo to find out why. Satellites are becoming increasingly important in communications and navigation. This makes us more vulnerable to the northern lights, especially within offshore and aviation. In a worst case scenario an aircraft can lose contact with its surroundings. Oil tankers can struggle with precise navigation. In order to more precisely predict when radio communications and navigation will fail, researchers require more information about what happens when violent solar winds hit the Earth and produce the northern lights......
