The thirteenth volume in the series presents all articles on the aurora borealis that were published in the journal of the Swedish Societas Literaria / Societas Regia Literaria et Scientiarum (now Kungl. Vetenskaps-Societeten i Uppsala) during its first decade of existence, from 1720 to 1729. The articles are by the adjunct/professor of astronomy in Uppsala, Erik Johan (Ericus Johannes) Burman; the professor of mathematics in Lund, Conrad (Conradus) Quensel; and the adjunct/professor of astronomy in Uppsala Anders (Andreas) Celsius. E. J. Burman developed a theory of two kinds of aurora borealis and inspired other investigators across Sweden to observe the phenomenon according to his instructions.
