Although the Sun is a huge gaseous body, the solar inner layers are not visible, with the opacity of the convection zone. Moreover, the surface events are related to or extended from the solar interior layers according to the previous study such as [12]. Is it possible that the location of the surface events are related to the inner layers? The aim of the study is to study the possibility of a relationship between the solar flares’ locations with the solar interior layers. The current study uses the angular central distance from the center of the solar dist to the solar flare’s location (distance) of X-Ray solar flares from GOES (during 1975-2021) and RHESSI (during 2002-2021). The distance curvature of this distribution demonstrates and reflects the solar interior layers with giving about 4 peaks. The primary and higher peak is about 15°-20° which demonstrates and reflects the edge of the solar core. Other peaks reflect other interior layers including radiative and convection zones. The solar core radius increases with increasing the strength of the solar cycle progressive, and vice versa.
