Descriptions of eleven aurorae observed in the Canary Islands during the period 1770--2010 have been found in different documents. Most of them are coincident with periods of strong solar activity, with the geomagnetic latitude playing a minor role. Coronal mass ejections are the most probable solar source of these
low-latitude events. The absence of low-latitude aurorae is verified in our sample during the Dalton Minimum and the first half of the 20th century.
