Description
Abstract. This research compiles and analyses information of solar flares data and variation of the actual space environment data from spacecraft for studying the concordances of the variation solar cycle. These information are the specifically solar flare events of X and M class in 23$^{rd}$ and 24$^{th}$ solar cycles. The number of X class flares of 23$^{rd}$ solar cycle more than 24$^{th}$ solar cycle. We found the highest X class flare of X28 on November 4$^{th}$, 2003 for 23$^{rd}$ solar cycle, and The highest X class flare of X9.3 on September 9$^{th}$, 2017. The highest solar wind velocity for these both solar cycles are 1020.9 and 750.6 km/s, respectively. The Kp index is an excellent indicator of disturbances in the Earth's magnetic field for solar flares of 23$^{rd}$ solar cycle more than 24$^{th}$ solar cycle. We found the most of solar events in 23$^{th}$ solar cycle occur in southern part of the Sun and the most of solar events in 24$^{th}$ solar cycle occur in northern, which that corresponded to the reverse of the Sun’s magnetic field for every 11 years. Overview: the violent of the solar flare events on the 23$^{rd}$ solar cycle higher than 24$^{th}$ solar cycle.
