The flares, which are eruptions of high-energy radiation on the surface of the sun, may cause satellite disruptions. While some tabloids – like the ironically named Sun – are claiming that the filmed blast is “expected to cause a massive geomagnetic storm when it reaches earth”, possibly knocking out power supplies, the more sober Telegraph quoted NASA’s solar dynamics observatory in their description of the flares as “visually spectacular”, but resulting in “fairly small” effects down here on terra firma. Check out the following ITN video report of the solar blast: See more video footage on the Telegraph’s website. SUBSCRIBE TO NEWSLETTER Thank you, your sign-up request was successful!
