Northern lights could be visible in Catalonia this weekend: How and where to watch

Seeing northern lights is extremely difficult, and many people travel to other countries such as Norway or Iceland just to have a chance to experience them. Spotting them in Catalonia is almost impossible.

But last May, Catalans were amazed when northern lights appeared in many parts of the territory. The skies were filled with the pinks, greens and blues typical of northern lights, and many were able to capture this extraordinary moment.

This rare phenomenon, the most intense display of the Northern Lights in Catalonia in 150 years, was triggered by a powerful solar storm. The Sun was in a cycle of heightened activity, releasing larger-than-usual solar flares.

Although this phenomenon poses no danger to the Earth, many solar particles reach our planet, which can cause the Northern Lights to appear at lower latitudes than usual.

Now this phenomenon could be repeated, as an alert for an intense solar storm has been activated again.

The most intense flow of particles is expected to reach the Earth after 8pm on Thursday (Catalan time), with the possibility of it continuing into Friday and Saturday night, although probably with less intensity.

However, expectations should be measured, as this is a highly unpredictable phenomenon. "The episode last May was historic, with almost no precedent. So it's wise to manage expectations, but it's worth keeping an eye on the sky," Catalan astronomer Joan Anton Català said on X. 

While the last Northern Lights were visible from many areas, especially at higher altitudes and in areas of low light pollution, they were even seen from Sabadell, near Barcelona.

However, mountainous areas are still the best places to see the Northern Lights. The areas of the Pyrenees, such as La Cerdanya, or astronomical parks such as Montsec and Prades are some of the best locations.

If you're in Barcelona, the Montseny range is the most recommended spot. From Girona, the coast is a good option, with Cap de Creus being another prime location.

For those wanting to catch a glimpse from an astronomical park, the one in Pujalt, near Cervera, central Catalonia, will open its doors for free tonight.
