论文摘要
本文介绍了19-24个活性周期的黑子几何特征的分析结果。根据黑子图像标准化的方法研究了黑子的形状，以研究该点的平均谱。研究了黑子形状与轴对称构型的偏差。发现这些斑点通常具有椭圆形的形状，而椭圆形的主要轴是对赤道的主要倾斜度，而赤道则在北半球和南半球相对。黑子轴的倾斜角对应于活性循环中双梁的倾斜角。在当前周期中黑子的形状与下一个活动周期的幅度之间的关系。沿斑点当前周期的经度的伸长越大，下一个活动周期的伸长越高。
The paper presents the results of the analysis of the geometric characteristics of sunspots for the period of 19-24 cycles of activity. The shape of sunspots was studied on the basis of the method of normalization of images of sunspots to study the average profile of the spot. The deviation of the shape of sunspots from the axisymmetric configuration is investigated. It was found that the spots, as a rule, have an ellipsoid shape, and the major axis of the ellipse has a predominant inclination to the equator, opposite in the Northern and Southern hemispheres. The angle of inclination of the sunspot axis corresponds to the angle of inclination of the bipoles in the activity cycles. The relationship between the shape of sunspots in the current cycle and the amplitude of the next cycle of activity is found. The greater the elongation along the longitude of the current cycle of spots, the higher the next cycle of activity will be.
