Flares outside sunspot groups
Abstract
Flare statistics for sunspot cycle 21 (1976-1984) were studied using data from the Soviet Solar Data Bulletin. Flares in spotless regions account for 6.6 percent of all flares, on the average; in years of minimum activity, the portion of such flares reaches 16.5 percent. Flares outside sunspot groups are mostly located near flocculi edges as well as in the vicinity of filaments.
