Cordova He also saw tonight a Northern LightsWithout a doubt, a privilege. An electromagnetic phenomenon that has been visible in the skies over a large part of Spain, passing from Andalusia to Catalonia, Aragon, Galicia and the Valencian Community, as various meteorological and astronomical observatories have published on social networks.

The State Meteorological Agency (Aemet) confirmed this morning that “polar auroras are being observed at very low latitudes in the northern hemisphere, including Spain” and that “there are many photographs that attest to this.”

He electromagnetic phenomenontypical of the polar regions, has also been captured in Córdoba and, for example, the Calar Alto Astronomical Observatory, in Almeriahas also reported on the phenomenon: “Once again we are honored with its presence by an aurora borealis in Calar Alto”, has published in Peña Trevinca, in the Orense region of Caballeda de Valdeorras.

This weekend the possible visualization of an aurora borealis in the skies of Spain was expected due to a great geomagnetic storm that the Earth is suffering. A similar phenomenon was seen in the Valencian Community in 2003, according to the meteorological services of the eastern peninsular region.

On the social network , bands, curtains, etc. Therefore, unlike normal weather phenomena, they form much higher in the troposphere, usually at an altitude of between 90 and 150 kilometers.

Auroras appear due to the interaction between the solar wind and the Earth’s magnetic field, according to Aemet. “The solar wind is strongest at times close to maximum solar activity, which occurs in cycles of between 10 and 12 years,” she explained.

Meteorology has reported that we are currently near the maximum of solar activity: sunspots indicate zones of solar magnetic activity associated with atmospheric solar flares and coronal mass ejections.

Polar auroras are due to the presence of electrically charged particles ejected from the sun (the solar wind), which act on rarefied gases in the upper layers of the atmosphere, according to the World Meteorological Organization.
