Description

Sometimes, strong solar energetic particle events can be observed by neutron monitors on the ground level, and this is commonly called a "Ground-Level Enhancement" (GLE) of their count rates over the background. Here we report a such event that happened on 8 June 2024 and was consequently numbered as #75. It was caused by a solar flare originating from the active region 13697 (13664 on the previous solar rotation), the same that caused the previous GLE #74. The reported GLE is weak, only few stations (DOMC, PWNK, SOPO) had shown statistically significant responses simultaneous with the enhanced proton flux seen in a space-borne particle detector data (GOES-16). In this work, we present the observed GLE and a reconstruction of spectra of SEP during it using neutron monitor data.
