ground level enhancements
MetadataShow full item record
On 10 September 2017, a ground level enhancement (GLE) of cosmic ray intensity, identified as GLE72, was recorded by several stations of the worldwide neutron monitor network provided by the high‐resolution Neutron Monitor Database. The solar proton event that resulted in this GLE was associated with active region AR2673, which produced an X8.2 flare on the solar west limb. Protons were measured by the GOES satellites with energies above 10, 50, and 100 MeV, while particles at higher energies above 500 MeV were registered by ground‐based neutron monitors. This GLE event was successfully detected in real time by the GLE Alert plus System of the Athens Neutron Monitor Station (A.Ne.Mo.S.). In this work an overview of the GLE72 event is given, and a detailed analysis of the evolution of the GLE Alert signal issued by the GLE Alert plus System as well as a postevent summary are presented.
