论文摘要
通过每天对太阳大规模磁场进行细致观察，Wilcox太阳观测站（WSO）已分类了两个太阳能活动的磁性（Hale）循环。这两个（约22年）的Hale周期产生了四个（$ \ sim $ 11年）的黑子周期（21至24号）。最近的研究强调了“扩展的太阳周期”（ESC）及其与基本Hale周期的联系的持久性 - 尽管是通过太阳光球，色球和Corona的图像分析所产生的大量代理。该简短的手稿介绍了ESC的对应关系，表面环形磁场演化以及Hale循环的演变。随着黑子周期25开始，鉴于天气尺度观测可以提供的潜在的预测能力，对观察映射的兴趣和扩展周期的兴趣不能更高。
Through meticulous daily observation of the Sun's large-scale magnetic field the Wilcox Solar Observatory (WSO) has catalogued two magnetic (Hale) cycles of solar activity. Those two (~22-year long) Hale cycles have yielded four ($\sim$11-year long) sunspot cycles (numbers 21 through 24). Recent research has highlighted the persistence of the "Extended Solar Cycle" (ESC) and its connection to the fundamental Hale Cycle - albeit through a host of proxies resulting from image analysis of the solar photosphere, chromosphere and corona. This short manuscript presents the correspondence of the ESC, the surface toroidal magnetic field evolution, and the evolution of the Hale Cycle. As Sunspot Cycle 25 begins, interest in observationally mapping the Hale and Extended cycles could not be higher given potential predictive capability that synoptic scale observations can provide.
