SOHO solar data (IMAGE) Southwest Research Institute Caption Using Solar and Heliospheric Observatory data, SwRI developed a tool to efficiently label large, complex datasets, such as the magnetogram on the left, to allow a machine learning application to identify potentially hazardous solar events. Solar flares, coronal mass ejections, prominences and sunspots are all driven by complex magnetic activity within the Sun’s interior and at its surface, illustrated by the ultraviolet image on the right.
