Abstract

One of the energetic environments under study in contemporary astrophysics is the solar environment. The term "solar activity" refers to physical phenomena that take place in the sun's outer atmosphere over the course of solar cycles 23, 24 and 25 . The solar cycle, also referred to as the solar magnetic cycle, is an almost change in the Sun's activity that lasts 11 years. The fundamental parameters that govern solar activity are sunspots, high-speed solar winds, solar flares, coronal mass ejections and Halo CME. The relationship between various features that are similar during solar cycles 23, 24 and 25 is examined in the current paper. According to the study, there is still a strong correlation between different parameters that point to a common origin. The factors affecting solar activity determine whether a cycle is at its maximum or minimum. From this study Compared to solar cycles 24 and 25, the annual averaged solar wind is at its highest during solar cycle 23. In solar cycle 23, the solar wind reached a maximum speed of 543 km/s, while in solar cycle 24, the maximum solar wind reached a speed of 455 km/s. The correlation of the yearly solar indices with sunspot number shows that mean value of the solar indices is minimal in solar cycle 24 and 25 with the maximum indices value as for the solar cycle 23.
