Abstract:

The relationship between the flaring rate and 8.6 mm brightness temperatures of active regions has been analyzed. As the 8.6 mm brightness temperature of an active region increases, the energy released by the region is contained in larger and larger flares. At low temperatures subflares are dominant, at intermediate temperatures most of the events are either subflares or class 1 flares and at high temperatures class 2 or greater flares release most of the energy. The results of the study indicate that measurements of 8.6 mm brightness temperatures can be used to predict the rate of flaring of active regions.
