A rare and fascinating atmospheric phenomenon known as Sprite (lightning) has captured the attention of scientists and skywatchers around the world.
Often described as a silent burst of light spreading across the tops of storm clouds, sprite lightning occurs high above thunderstorms in the upper atmosphere. The phenomenon typically appears as a brief flash of reddish or orange light and lasts only a few milliseconds, making it extremely difficult to observe or photograph.
What are sprite lightning events?
Sprites are a type of transient luminous event (TLE) that occurs between about 50 and 90 kilometres above the Earth’s surface.
Unlike ordinary lightning, which travels between clouds and the ground, sprites occur above thunderstorms and are triggered by powerful lightning strikes below.
Because of their altitude and short duration, sprites are rarely seen with the naked eye and usually require high-speed cameras or specialised equipment to capture.
A fleeting yet spectacular phenomenon
Sprites often appear as jellyfish-shaped or column-like flashes of light, spreading rapidly across the upper atmosphere.
The flashes last for just a fraction of a second, making them one of the most elusive natural light phenomena in the sky.
Scientists believe these events play a role in transferring electrical energy from thunderstorms into the upper atmosphere, although research into their exact mechanisms is still ongoing.
A discovery that changed atmospheric science
Sprites were first documented by scientists in 1989, when researchers accidentally recorded them while observing distant thunderstorms.
Since then, observations from ground-based cameras, aircraft, and satellites have helped scientists better understand how these mysterious flashes occur.
Researchers say studying sprites could provide important insights into atmospheric electricity, climate interactions, and the dynamics of thunderstorms.
A rare sight for skywatchers
Because they occur high above clouds and last only milliseconds, witnessing sprite lightning in real time is extremely rare.
However, photographers and researchers who manage to capture the phenomenon often describe it as a breathtaking moment of natural beauty — a fleeting flash illuminating the upper atmosphere far above the storm below.
