Aurora borealis from the Mirador de la Figuerassa, on May 10, 2024, in Cercs, Barcelona, Catalonia (Spain). Catalonia recorded aurora borealis last night, May 10, to today. An aurora borealis is produced by a very powerful solar storm, which collides with the Earth's magnetic field. To the north of the Earth these phenomena can be seen more easily, but on this occasion they have been seen in several points of Spain, Europe and even Africa, where it is very rare to be recorded. 11 MAY 2024 Lorena Sopêna / Europa Press 05/11/2024 (Europa Press via AP)
