In early September 2017, during solar minimum, Active Region 12673 produced 26 M-class and four X-class flares. Gamma-ray emission >100 MeV was observed by the Fermi Large Area Telescope (LAT) for several hours following the X8.2 flare that began at 15:35 UT on September 10 when the active region was at or beyond the solar limb. It was associated with an ~1700 km/s coronal mass ejection (CME)...

We study the spatial and temporal evolution of coronal shock properties inferred from observations to see if they could be the source of the particles producing the γ‐rays and the strongest Solar Energetic Particles (SEPs) measured in situ. Greater than 100 Mev γ‐rays measured in the minutes to hours following solar flares suggest that high‐energy particles interacting in the solar atmosphere...

The Alpha Magnetic Spectrometer (AMS) experiment was installed on the ISS on May 19, 2011, during the ascending phase of solar cycle 24. It will take measurements until the end of ISS operations, into the rise of solar cycle 25. It is the largest experiment capable of directly measuring Solar energetic particles (SEPs) with energies of about a few hundred MeV and above. In its first five years...
