论文摘要
在这里，我们介绍了在太阳周期期间24中北南（N-S）分布（N-S）分布（N-S）分布和不对称的研究结果。在周期中，双峰（2011年，2014年）的太阳能最大值发生了。 2011年的周期峰值是由于北半球（NH）的B级耀斑过量活性引起的，而C和M级别的南半球（SH）中的C和M级活动支持了2014年周期的第二个峰值。数据分析表明，SXR耀斑在每个半球上更为明显。 SXR耀斑计数的累积值在周期的上升阶段显示出北部的过量。但是，在周期的下降阶段，南部过剩。在周期中，存在明显的SH主导的不对称性。在循环的最大值接近，不对称会显着增强并在符号中逆转。
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.
