The Solar Energetic Particles (SEPs) are high-energy particles coming from the Sun. They consist of protons, electrons and HZE ions, with energy ranging from a few tens of keV to many GeV. They are of particular interest and importance because they can endanger life in the outer space (especially particles above 40 MeV). But, their onset is extraordinarily hard to predict, in part because we still do not know exactly where on the Sun they come from. The greatest mystery about gradual SEPs is not what speeds them up, but where they come from in the first place. For reasons still not fully understood, the SEPs contain a different mix of particles than the other solar material streaming off the Sun in the solar wind – fewer carbon, sulphur and phosphorous ions, for instance. Many scientists thought the SEPs would be found at the edges of the active region where the magnetic field is already open and material can escape directly. But, the fingerprint matched only in the regions where the magnetic field is still closed. The SEPs had, somehow, broken free from strong magnetic loops connected to the Sun at both ends. These loops trap material near the top of the chromosphere, one layer below where solar flares and coronal mass ejections erupt.
