Low and mid geomagnetic latitude aurora observations provide information about episodes of intense solar storms associated with flares and outstanding coronal mass ejection (CME) and about the variation of the geomagnetic field. However, for many observers at mid and low latitudes, the features of a northern light were unknown, so they could easily report it as a phenomenon without explanation. In this work, we found that an earlier mid geomagnetic latitude aurora was observed in Beaus jour, close to B ziers (43°190 N, 3°130 E), France, by the abbot Fran ois Rozier. He was a meticulous botanist, doctor and agronomist with a special interest in atmospheric phenomena. On 15 August 1780, from 19:55 to 20:07 (Universal Time), Fran ois Rozier observed a phosphoric cloud . A careful analysis of the report indicates that he was reporting an auroral event. The recovery of auroral events at low and mid latitude during the 1780s is very useful for shedding light on solar activity during this period because there are few records of sunspot observations. 000097152 536__ $$9info:eu-repo/grantAgreement/ES/MICINN/PID2019-108589RA-I00 000097152 540__ $$9info:eu-repo/semantics/openAccess$$aby$$uhttp://creativecommons.org/licenses/by/3.0/es/ 000097152 590__ $$a1.88$$b2020 000097152 591__ $$aASTRONOMY & ASTROPHYSICS$$b42 / 68 = 0.618$$c2020$$dQ3$$eT2 000097152 591__ $$aGEOSCIENCES, MULTIDISCIPLINARY$$b140 / 198 = 0.707$$c2020$$dQ3$$eT3 000097152 591__ $$aMETEOROLOGY & ATMOSPHERIC SCIENCES$$b75 / 94 = 0.798$$c2020$$dQ4$$eT3 000097152 592__ $$a0.522$$b2020 000097152 593__ $$aAstronomy and Astrophysics$$c2020$$dQ2 000097152 593__ $$aAtmospheric Science$$c2020$$dQ2 000097152 593__ $$aSpace and Planetary Science$$c2020$$dQ2 000097152 593__ $$aGeology$$c2020$$dQ2 000097152 593__ $$aEarth and Planetary Sciences (miscellaneous)$$c2020$$dQ2 000097152 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/publishedVersion 000097152 700__ $$0(orcid)0000-0003-3085-7040$$aDominguez-Castro, F. 000097152 700__ $$aDe Ferri, L. 000097152 773__ $$g38, 6 (2020), 1139-1147$$pAnn. geophys.$$tANNALES GEOPHYSICAE$$x0992-7689 000097152 8564_ $$s314059$$uhttps://zaguan.unizar.es/record/97152/files/texto_completo.pdf$$yVersión publicada 000097152 8564_ $$s503530$$uhttps://zaguan.unizar.es/record/97152/files/texto_completo.jpg?subformat=icon$$xicon$$yVersión publicada 000097152 909CO $$ooai:zaguan.unizar.es:97152$$particulos$$pdriver 000097152 951__ $$a2021-09-02-10:32:16 000097152 980__ $$aARTICLE
