The relationship between Cosmic ray intensity with Geomagnetic activity in Solar Cycle 23 and ascending phase of cycle 24

Abstract

Collisions between Earth's atmosphere and cosmic rays, which originate in space, release very energetic particles. Space weather and cosmic rays from 1996–2022, influenced by solar variability are examined in this research. The modulation of cosmic rays may be either periodic or random. Forbush decline, temporary dip, and ground level enhancement (GLE) are all instances of sporadic categories. While Forbush reduction describes short-term variance, galactic cosmic ray variation describes long-term fluctuation. A long-term trend of cosmic ray strength has been observed, with a peak occurring once every eleven years. The strength of cosmic rays is inversely related to solar activity. From 22–25 solar cycles, many parametric relationships between the sun and geophysical variables were studied. Investigating the effects of several sunspot cycles on the terrestrial plasma environment via changes in the solar characteristics that matter most. Furthermore, it seeks to investigate the relationship between the sunspot maximum's impact on geomagnetic activity and its amplitude. There is a clear change in the geomagnetic activity index that lines up with the sunspot cycle, which occurs every eleven years. However, solar flare maximums do not correspond to the peak of geomagnetic activity as measured over 27 days. From 22–25 solar cycles, geomagnetic indices correlate with parameters V and B. Both Ap and Kp follow a similar pattern of variation throughout the solar cycle's peak.
