Understanding and predicting solar flares

23 octubre 2014

Scientists have identified a key phenomenon in the triggering of solar flares. Using satellite data and models, the scientists were able to monitor the evolution of the solar magnetic field in a region with eruptive behavior. Their calculations reveal the formation of a magnetic rope1 that emerges from the interior of the Sun and is associated with the appearance of a sunspot. They show that this structure plays an important role in triggering the flare.
