前望远镜历史文献中的太阳黑子和极光观测记录可以提供有关过去太阳活动的有用信息。对于极端太空天气事件也是如此，因为它们可能被记录为肉眼观察到的大型太阳黑子或低纬度极光。在本文中，我们介绍了对《宋史》（一部跨越十世纪至十三世纪的中国正式编年史）中太阳黑子和极光记录的全面调查的结果。这份编年史包含了根据政府政策进行的连续观察记录和格式良好的报告。提供了太阳黑子和极光观测频率与作为相应时期太阳活动指标的放射性同位素观测频率的简要比较。本文是我们项目的第一步，我们在该项目中调查并汇编了来自不同地点和语言的历史文献中的太阳黑子和极光记录，最终将其作为在线数据提供给科学界。
Records of sunspot and aurora observations in pre-telescopic historical documents can provide useful information about solar activity in the past. This is also true for extreme space weather events, as they may have been recorded as large sunspots observed by the naked eye or as low-latitude auroras. In this paper, we present the results of a comprehensive survey of records of sunspots and auroras in the Songshi, a Chinese formal chronicle spanning the tenth to the thirteenth century. This chronicle contains a record of continuous observations with well-formatted reports conducted as a policy of the government. A brief comparison of the frequency of observations of sunspots and auroras and the observations of radioisotopes as an indicator of the solar activity during corresponding periods is provided. This paper is the first step of our project in which we survey and compile the records of sunspots and auroras in historical documents from various locations and languages, ultimately providing it to the science community as online data.
