Short summary
Low-latitude aurorae (LLA) were an uncommon phenomenon not well known or understood in 1780. During our historical manuscript research of high atmospheric phenomena, we came across a document reporting an observation made by the abbot Rozier in Beausejour, France, on 15/08/1780. Thanks to the accuracy of his report, we were able to confirm it was a white, two-band structure LLA. Due to the few existing geomagnetic and solar observations, this is useful new geomagnetic activity proxy data.
