  • Can ripples on the sun help predict solar flares?

    Scientists discovered in 1996 that sunquakes are linked to solar flares. Now, using helioseismic holography, scientists have analyzed a 2011 flare and shown that the impulsive source that generated the sunquake, and the refracted acoustic waves that later rippled the solar surface, was submerged 1,000 kilometers below the photosphere and flare. Further sunquake study could reveal if submerged sources are common and whether they can predict the appearance of flares and potential impact on Earth.
