Abstract Here we present the results of the study of the north-south (N-S) distribution and asymmetry of GOES soft X-ray (SXR) flares during solar cycle 24. The period of study includes ascending, maximum and descending phases of the cycle. During the cycle double-peaked (2011, 2014) solar maximum has occurred. The cycle peak in the year 2011 is due to B-class flares excess activity in the northern hemisphere (NH) whereas C and M class flares excess activity in the southern hemisphere (SH) supported the second peak of the cycle in 2014. The data analysis shows that the SXR flares are more pronounced in 11 to 20 degree latitudes for each hemisphere. Cumulative values of SXR flare count show northern excess during the ascending phase of the cycle. However, in the descending phase of the cycle, southern excess occurred. In the cycle a significant SH dominated asymmetry exists. Near the maximum of the cycle, the asymmetry enhances pronouncedly and reverses in sign.

太阳活动周期 24 期间 GOES SXR 耀斑的南北分布和不对称性

摘要 在这里，我们介绍了太阳活动周期 24 期间 GOES 软 X 射线（SXR）耀斑的南北（NS）分布和不对称性的研究结果。研究周期包括周期的上升、最大和下降阶段。在周期双峰（2011 年，2014 年）期间，太阳活动的最大值已经发生。2011 年的周期高峰是由于北半球 (NH) 的 B 级耀斑过度活动，而南半球 (SH) 的 C 和 M 级耀斑过度活动支持了 2014 年的第二个周期高峰。 数据分析表明，SXR 耀斑在每个半球的 11 到 20 度纬度上更为明显。SXR 耀斑计数的累积值显示在周期的上升阶段北方过剩。然而，在周期的下降阶段，出现了南方过剩。在循环中存在显着的 SH 主导的不对称性。在周期的最大值附近，不对称性显着增强并且符号反转。
