ABSTRACT

Solar flares tend to occur above sunspot groups. In this paper, four solar active regions are selected for observation, among which the AR13190 and AR13213 solar active regions are the main observation regions, and AR13182 and AR13184 are the brief observation regions. In this paper, the formation and evolution of sunspots and flares and the changes of solar structure before and after the eruption of flares are investigated, and the conclusion is that sunspots can affect the formation of the upper chromosphere atmosphere and flares, and solar flares can affect the structure of sunspots. Such research could also be applied to the prediction of solar flares.
