Monitoring Heliosphere, Magnetosphere, and Atmosphere Via Cosmic Ray Effects in 2018 August

From the data (uncorrected for temperature effect) of the global network of neutron monitors (GNNM), along with the data of the Yakutsk muon telescope suite and the URAGAN muon hodoscope (Moscow), we applied a modified spectrographic global survey (SGS) for the 2018 Aug event to split cosmic ray variations into components of primary, magnetospheric, and atmospheric origin. Obtained were the time evolutions for the different-rigidity primary particle isotropic flux, pitch-angle anisotropy of cosmic rays (CRs), and interplanetary magnetic field (IMF) orientation. We provide variations in the rigidity of the geomagnetic cutoff (RGC) in Irkutsk and in the average bulk temperature at the points that observe charged components.
