Aurora provides an essential diagnostic to spatial and temporal variations of terrestrial space environment and is also an important proxy of solar and geomagnetic activities. Contemporary auroral observations have just continued for more than half a century. Visual auroral phenomena recorded in historical books provide key clues to understand the solar and geomagnetic activities in the long history prior to modern era. In this study, we compiled a new auroral catalog from ancient Korean historical books, including 2013 auroral records with day‐level resolution from 1012 to 1811 CE, especially for the records searched from the Seungjeongweon Ilgi. The number of auroral records in this new catalog is greatly enlarged compared with previous lists. The occurrence of the aurora in the new catalog is generally consistent with previous data sets. This extended data set provides valuable support for various studies related to solar‐terrestrial space weather and ancient climates in the past millennium.

韩国历史书籍编纂的古代极光记录

极光为陆地空间环境的时空变化提供了必要的诊断方法，也是太阳和地磁活动的重要替代。当代的极光观测仅仅持续了半个多世纪。历史书籍中记录的视觉极光现象为了解近代历史悠久的太阳和地磁活动提供了重要线索。在这项研究中，我们从韩国古代史书中编制了一个新的极光目录，包括2013年极光分辨率的1012年至1811年的极光记录，尤其是针对从承定云一日纪检索的记录。与以前的列表相比，此新目录中的极光记录数量大大增加。新目录中极光的出现通常与以前的数据集一致。这个扩展的数据集为过去千年中与太阳陆地空间天气和古代气候有关的各种研究提供了宝贵的支持。
