The sixteenth volume in the series presents all articles on the aurora borealis that were published in the journal of the Swedish Societas Regia Literaria et Scientiarum (now Kungl. Vetenskaps-Societeten i Uppsala) covering the years 1730 to 1739. The articles are by the society’s secretary, the professor of astronomy in Uppsala, Anders (in Latin: Andreas) Celsius and five other Swedish professionals and amateurs of science. In the introduction to this volume, neo-Latinist and historian of science Per Pippin Aspaas summarizes the contents of all articles dealing with the aurora and presents extracts of these texts in English translation. He also provides a short history of the society in the period and gives brief presentations of Anders Celsius, Herman Spöring, Sven Hof, Johan Göstaf Hallman, Johan Sparschuch and Nils Wallerius as auroral researchers.
