WebMar 31, 2024 · Solar flares usually take place in active regions, which are areas on the Sun marked by the presence of strong magnetic fields; typically associated with sunspot groups. As these magnetic fields evolve, they can reach a point of instability and release energy in a variety of forms. WebThe flares have relative intensities in the range 1-100 parts per thousand and typical durations of a few minutes to several hours. The mean interval between flares varies between 1 and 120 days. We estimate the typical energy of flares to be around 10 35 erg in the F-type stars and about 10 36 erg in the A-type stars. grant clinton mansfield ohio
