Variation Spectra and Anisotropy of Cosmic Rays during Forbush Effects in March 2023

Based on ground-based observations of cosmic rays (CRs) on the global network of neutron monitors, the Yakutsk complex of muon telescopes, and the URAGAN muon hodoscope (Moscow), the spectra of CR variations and anisotropy during the Forbush effects of March 15 and 23, 2023 were calculated using the spectrographic global survey method. It is shown that the spectrum of CR variations during these periods is not described by a power function in a wide range of rigidities. It was found that the Earth was in a loop-shaped structure of the interplanetary magnetic field on March 15 and that it entered a magnetic cloud with closed field lines on March 23.
