Video shared by X user Joan Anton Català Amigó captures a lightning strike on a well-known communications tower in Barcelona during a storm on September 21, 2025. The footage was recorded from the Fabra Observatory.

The clip illustrates the intensity of the storm season, which has led to significant disruptions and forced the postponement of events amid storm alerts.

This lightning strike is part of a wider series of extreme weather events across Europe, including floods in Italy and France and wildfires in Spain.

The Fabra Observatory, founded in 1904 and renowned for its astronomical research, provided a clear vantage point to document the dramatic event.

Joan Anton Català Amigó called it a “fortunate sequence captured that evening from the Fabra Observatory in Barcelona.”
