This study looks at the relationship between X-class solar flares and geomagnetic indices over the course of Solar Cycle 25, from the solar minimum to the solar maximum. X-class solar flares are the most powerful solar outbursts, having considerable impact on space weather, altering both the Earth's ionosphere and geomagnetic environment. This study focuses on the temporal variation in the occurrence of these flares and their relationship with geomagnetic indices such as the Dst, Kp and Ap indices. These indices serve as an indicator of the geomagnetic activity. Examining flare events from the beginning of Solar Cycle 25 to its maximum phase identifying trends and patterns in flare frequency and intensity and linking them to geomagnetic disturbances reported over the same time period. These findings highlight the dynamic interplay between solar activity and geomagnetic reaction, providing insights into the space weather conditions that are expected as the solar cycle progresses. This investigation presents useful information for space weather forecasting and the potential effects on satellite operations, communication systems, and power grids on Earth. This research offers valuable information for space weather forecasting and the potential impacts on satellite operations, communication systems, and power grids on Earth.
