Horizon

Scientists are expecting a fit of violent activity on the sun which will propel billions of tonnes of superheated gas and pulses of energy towards Earth. They have the power to close down our modern technological civilisation - indeed in 1989, a solar storm cut off the power to Quebec. `Horizon' meets the space weathermen trying to predict what's coming our way, and organisations who are preparing for the impending solar storms.
