VAQUERO, José Manuel; GALLEGO, María Cruz  e  DOMINGUEZ-CASTRO, Fernando. A possible case of Sporadic Aurora in 1843 from Mexico. Geofís. Intl [online]. 2013, vol.52, n.1, pp.87-92. ISSN 2954-436X.

In recent years, some authors have shown that some auroras can be observed at relatively low latitude when the geomagnetic activity is quiet or moderate. This very special type of aurora is called "sporadic aurora". We present and analyze in this work a possible case of "sporadic aurora" observed in Mexico on the 19 April 1843. Moreover, we study the solar and auroral activity around this event.

Palavras-chave : Sporadic aurora; geomagnetic activity; solar activity; Mexico; history of Geophysics.
