Flare Production Potential of Sunspot Groups Based on Their Modified Zurich and Magnetic Classifications
摘要
Sunspot groups are classified into two different ways based on their morphology and evolution (Modified Zurich Classification) and magnetic properties of sunspot groups (Mount Wilson magnetic classification) systems. The modified Zurich classification system is based on three different parameters; the first parameter describes the morphology and evolution of a group, the second parameter describes the shape of the biggest spot in the group, the third one describes the distribution of spots inside a sunspot group and each parameter is divided into sub groups. Here, we used the classes in the third parameter of modified Zurich Classification system and all classes in the Mount Wilson Magnetic classification system. Then we calculated the flare production potential of all classes from the year 1996 to 2023. Our main findings are as follows: (i) More than 50% of all X flares are produced by the compact groups “c” of McIntosh classification and Beta-Gamma-Delta class of magnetic classification systems, (ii) least number of flares are observed in the “x” class of McIntosh classification and alpha class of magnetic classification system, and (iii) “x” McIntosh and alpha magnetic classes are quite compatible with each other in terms of producing flares.
