Cosmic Ray Ground Level Enhancement on August 24, 1998

  • Published:
Bulletin of the Russian Academy of Sciences: Physics Aims and scope

Abstract

We address variations in the rigidity spectrum and anisotropy of cosmic rays (CRs) during the 1998 Aug 24 Ground Level Enhancements (GLEs) from the satellite (GOES-10) and ground-based observations at the global network of neutron monitors by using the Spectrographic Global Survey techniques. We also determined CR differential rigidity spectra for different hours of the investigated event. The accelerated proton maximal rigidity in the GLE was shown to be 2.5 GV.
