Studying solar flares and their characteristics is significant for understanding the dynamics of the sun. In this work, a new view for studying the duration time of solar flares is presented. Regarding the analysis of the duration time, one of the solar flares parameters is introduced for the solar cycles 23 and 24. This is done by ordering the duration time of solar flares into five groups of minutes (<30, 30-60, 60 90, 90-120, >120) and calculating the total annual duration time of solar flares for each group. The total annual duration time is also calculated for each class of solar flare classification (B, C, M, X). Their relationship with both F10.7 and Kp-index are also studied. We found that approximately 41% of solar flares occur within 6-12 minutes for both solar cycles. Additionally, the total average of their duration time is 19.1 and 19.6 minutes, respectively.
Also, the average duration time of the ascending phase is less than the descending phase of both solar cycles for all classes of solar flares, except for B-class, which is vice versa. The relationship between the duration time of solar flares with F10.7 is strong. In contrast, the relationship with the Earth’s magnetic field is weak.
El estudio de las fulguraciones solares y sus características es importante para entender la dinámica del sol. En este trabajo se presenta una nueva visión para el estudio del tiempo de duración de las fulguraciones solares. En cuanto al análisis del tiempo de duración, se introduce uno de los parámetros de las fulguraciones solares para los ciclos solares 23 y 24. Esto se hace ordenando el tiempo de duración de las fulguraciones solares en cinco grupos de minutos (<30, 30-60, 60-90, 90-120, >120) y calculando el tiempo de duración total anual de las fulguraciones solares para cada grupo. También se calcula el tiempo de duración total anual para cada clase de clasificación de las fulguraciones solares (B, C, M, X). También se estudia su relación con el F10.7 y el índice Kp. Encontramos que aproximadamente el 41% de las fulguraciones solares se producen en 6-12 minutos en ambos ciclos solares. Además, la media total de su tiempo de duración es de 19,1 y 19,6 minutos, respectivamente. Asimismo, el tiempo medio de duración de la fase ascendente es menor que el de la fase descendente de ambos ciclos solares en todas las clases de fulguraciones solares, excepto para la clase B, que es viceversa. La relación entre el tiempo de duración de las fulguraciones solares con F10.7 es fuerte. En cambio, la relación con el campo magnético de la Tierra es débil.
