Happy Solar Flare

Via the Telegraph:
NASA's Solar Dynamics Observatory has captured dramatic footage of a powerful X-class solar flare erupting on the surface of the Sun. Harmful radiation from a flare cannot pass through Earth's atmosphere to physically affect humans on the ground, however – when intense enough – they can disturb the atmosphere in the layer where GPS and communications signals travel. This flare was classified as an X1.8-class flare – X-class denotes the most intense flares, while the number provides more information about its strength.
