Abstract

The high-speed solar wind is one of the main reasons for disturbances in the interplanetary magnetic field during years of low solar activity. These disturbances lead to modulations of cosmic ray fluxes that penetrate the Earth’s magnetosphere. This work presents results from analyzing disturbances in the angular distribution of cosmic rays in the GSE system registered by the URAGAN muon hodoscope for years of geomagnetic disturbances during the periods of solar activity minima in 2009–2010 and 2018–2019.
