Description

The surprising increase in solar activity in 2024, following a relatively tranquil 24th cycle, suggests that we are approaching the solar maximum of the 25th cycle. The complex interplay between disturbed interplanetary and geomagnetic fields affects the cosmic rays reaching the Earth’s surface in various ways.
Positioning the particle spectrometers at elevated altitudes, which analyze the energy spectra of muons and neutrons, is a strategic decision aimed at comprehending the intricate interactions between colliding interplanetary and geomagnetic fields and the solar proton accelerators. Direct comparison between the measured energy spectra of secondary neutrons and muons (MeV) via appropriate simulations is related to energy spectra of solar energetic protons (GeV).
The report highlights advanced instrumentation and data analysis methods to investigate solar-induced phenomena in cosmic rays by analyzing the solar events of the 25th cycle.
