Kirch published observations of the aurora borealis under her own name in 1707.
In 1707, Maria Margaretha Kirch published observations of the aurora borealis under her own name. Although the exact day is not documented in the available sources, the publication itself is an important marker of her independence as a scientific author.
Publishing under her own name mattered in a period when women’s observations were often filtered through fathers, husbands, or institutional patrons. Kirch’s willingness and ability to attach her own identity to her work demonstrates that she was not merely assisting another astronomer; she was contributing original observations to the scientific culture of her day. The aurora borealis was a striking and still scientifically puzzling phenomenon, and published reports helped create the empirical record on which later interpretation depended.
This achievement also shows that Kirch’s reputation did not rest solely on the comet of 1702. She was an active observational astronomer who participated in the broader early modern practice of cataloguing celestial events, helping transform the night sky into a site of systematic scientific knowledge.
