Photographer Captures Rare Red Sprites Flashing Above Mediterranean Thunderstorms

New Delhi, Oct 12, 2026 16:10 ISTMassive red pillars of light appearing to fall from the sky have been captured in a rare photograph over the Mediterranean, revealing a spectacular electrical phenomenon that occurs high above powerful thunderstorms.

French photographer Florian Riou captured the unusual display from Corsica, near the village of Calvi, after carefully predicting thunderstorm activity off the coast of Spain. The photograph shows red, pillar-like flashes high above distant storm clouds, resembling giant streaks of light descending from space.

Riou stated on LinkedIn that he had studied the location of thunderstorms and calculated viewing angles from different positions before attempting the shot. He identified a possibility of capturing the village of Calvi alongside brief luminous phenomena occurring over thunderstorms approximately 500 to 700 kilometers away, resulting in a rare glimpse of red sprites among the most elusive electrical phenomena in Earth's atmosphere.

Red sprites are short-lived electrical discharges that occur high above thunderstorm clouds, typically at altitudes of around 50 to 90 kilometers. They form in the upper atmosphere, in the region extending towards the mesosphere, rather than between clouds and the ground like ordinary lightning.

These flashes are triggered by powerful lightning discharges below. The resulting electric field accelerates electrons in the upper atmosphere, exciting molecules in the surrounding gas and causing them to emit light.

Sprites usually appear red because of the emission from molecular nitrogen. Their shapes can vary dramatically, appearing as vertical pillars, branching threads, or structures resembling jellyfish. Despite their enormous size, these flashes last only a few milliseconds and can extend tens of kilometers vertically, making them spectacular but extremely difficult to observe and photograph.

Red sprites are often hidden by thunderstorm clouds when viewed from the ground, and their brief duration means photographers must capture the right moment over distant storms under favorable conditions. Unlike familiar lightning bolts, sprites occur far above clouds, do not strike the ground, and result from atmospheric gas molecules becoming excited by energetic electrons rather than acting as streams of hot plasma.

Scientists obtained the first convincing instrumental evidence of sprites in 1989, helping establish that these unusual flashes were real atmospheric events rather than visual illusions.
