This study presents a comprehensive correlation analysis of key parameters associated with solar activity and geomagnetic storms throughout 2023, aimed at elucidating their interrelationships. The parameters investigated include the Disturbance Storm Time (Dst) index, intensities of C-class and B-class solar flares, sunspot numbers (SSN), and the 10.7 cm solar radio flux. Employing Pearson's correlation analysis, a robust statistical technique, the research quantifies the strength and direction of associations between these variables. The findings reveal positive correlations between the Dst index and C-class flare intensity (r = 0.1458), sunspot numbers (r = 0.2360), and the 10.7 cm solar radio flux (r = 0.3441), implying that increased solar activity corresponds to more intense geomagnetic disturbances. Conversely, a negative correlation is observed between the Dst index and B-class flare intensity (r = -0.3740). Strong positive correlations are also identified between sunspot numbers and C-class (r = 0.4278) and B-class (r = 0.5879) flare intensities, as well as the 10.7 cm solar radio flux (r = 0.8425). The results contribute to a deeper understanding of the Sun-Earth connection and have significant implications for space weather forecasting, risk assessment, and the development of mitigation strategies against adverse space weather events. | | Keywords : | | | 10.7 cm solar radio flux, sunspot numbers (SSN), Disturbance Storm Time (Dst), solar flares (SF) |
