Sunspot region 2422, M-class solar flares
Sunspot region 2422 has been slowly growing the past few days and quickly gained a Beta-Gamma-Delta magnetic layout during the past few days. This resulted in two M-class solar flares today: M1.0 and M1.9. None of these events were eruptive and no coronal mass ejections were launched. Can we expect more strong solar flares?
