An Analysis of the X1.59 Flare and Associated Events on 3rd July 2021

Solar flares are caused by a complex magnetic field on the surface of the Sun, which releases a large amount of radiation. We present an analysis of the X1.5 flare that occurred on 3rd July 2021 at 14:29 UT from the active region AR 2838. It was believed that some other events were related. Prior to satellite communication, the ionosphere was commonly used for radio communication. In case of enhanced excess photoionization due to solar activities, the D layer will not disappear after sunset. This includes the burst of the day, as well as the ionospheric response caused by the flare event. Although numerous studies have been conducted on the sun, its dynamic behavior has continued to draw the interest of astrophysicists to this area to this day.
