All the flares observed by the <a href="http://sdo.gsfc.nasa.gov/"> Solar Dynamics Observatory</a>, which takes more data than any other NASA satellite in history, are plotted here in a <a href= "https://en.wikipedia.org/wiki/Stereographic_projection"> standard stereographic projection</a> with <a href="http://d3js.org/" target="_blank">D3</a>. In the absence of a definitive theory of flare physics, the best hope for forecasting flares lies in analyzing our vast data set for observational clues. <a href= "http://arxiv.org/abs/1411.1405"> One way</a> is to use artificial intelligence.
