Description
On October 10-11, 2024, a severe geomagnetic storm (G4) was recorded during the 25th soral cycle accompanied by a Forbush decrease in galactic cosmic ray intensity. In this study, a detailed analysis of this severe event in regard to the accompanying solar activity, interplanetary conditions and solar energetic particle events is provided. The Forbush decrease during this storm is analyzed. The cosmic ray spectral analysis during the Forbush decrease of October 2025 was performed following the technique of Wawrzynczak and Alania (2010). Specifically in this technique the galactic cosmic ray spectral index was calculated using the coupling coefficient method. A yield function by Xaplanteris et al. (2021) based on the Quantum Field Theory (QFT) was applied in the spectral analysis of the Forbush decrease. Moreover, the result of NKUA“apPrediction tool” concerning this storm events is presented.
