摘要

提出了太阳黑子面积月平均值的重建方法——太阳活动的物理指标。对显著性水平\(\alpha = 0.05\)所得值的不确定性进行了估计。月均数的持续时间为275年。结果表明，AR指数在用小型望远镜进行历史观测重建太阳活动时，比黑子数指数或黑子群指数更有优势。该指数对可能失去的小群体并不敏感，这些群体平均约占总数的三分之一。

Monthly Mean Sunspot Areas in the Last 275 Years

A reconstruction of the average monthly values of sunspot areas—the physical index of solar activity—is proposed. The uncertainty of the obtained values for a significance level \(\alpha = 0.05\) is estimated. The duration of the number of monthly means has become 275 years. It is shown that the AR index, when used in reconstructions of solar activity of historical observations with small telescopes, is more advantageous than the indices of the number of spots or groups thereof. This index is not sensitive to the possible loss of small groups, which on average make up about a third of the overall number.

期刊介绍： Geomagnetism and Aeronomy is a bimonthly periodical that covers the fields of interplanetary space; geoeffective solar events; the magnetosphere; the ionosphere; the upper and middle atmosphere; the action of solar variability and activity on atmospheric parameters and climate; the main magnetic field and its secular variations, excursion, and inversion; and other related topics.
