Aurora happens on the earth, which closely varies with solar activity, providing a meaningful way to investigate solar activity variations, especially for the periods when the solar activity dataset is sparse. This study has compared and analyzed the auroral records observed in Korea and the mid-latitude region of Europe from 1610 to 1810 AD. Korean and European aurora records show consistency with solar activity variations, and each has its advantages in characterizing solar activity in certain periods. Before 1700 AD, the occurrence of Korean aurora was more abundant than that of the European aurora and was relatively consistent with the solar activity proxies. After 1700 AD, the European aurorae became more affluent and consistent with solar activity, while the Korean aurorae became sparse. The Korean aurora has unique advantages in characterizing the solar activity variations around the solar cycle scale during the Maunder minimum.
