If we are lucky, it will be another great light show overhead tonight. A pair of solar blasts have sent a cloud of magnetized gas into space, triggering a strong geomagnetic storm.
That's what causes the northern lights.
The Space Weather Prediction Centre of the National Oceanic and Atmospheric Administration has a website that predicts the spectacle and where it can be seen from.
