ABSTRACT

Severe solar eruptions pass through the heliosphere and reach the vicinity of the earth, which will have an impact on aviation and technology. Two typical solar active regions were selected to study the relationship between the evolution of active regions and solar eruptions. One of the active regions is AR 13229, which created 1 X-class flare, 2 M-class flares. The other active region is AR 12673, which created 4 X-class flares, 27 M-class flares. We found that new emerging magnetic flux in photosphere induced the changes of higher atmosphere (chromosphere and corona), which triggered the creation of big solar flares. The result can help us predict space weather.
