Capturing the Mysteries of the Sky: The Rare Dual Event of ELVE and Sprite

In a remarkable display of nature’s power, a strong lightning bolt recently struck over the Adriatic Sea, triggering two rare atmospheric phenomena that were photographed simultaneously above Possagno, Italy. The stunning image was captured by Valter Binotto, an award-winning photographer celebrated for his ability to document elusive atmospheric events.

The phenomena in question are known as an ELVE (Emission of Light and Very low-frequency perturbations due to Electromagnetic pulse sources) and a sprite. The ELVE appears as a red, disk-like structure, while the sprite takes on a jellyfish-like form with its tentacle-like flashes. This unique photographic achievement highlights the beauty and mystery of transient luminous events (TLEs), which are quick, bright phenomena that occur in the upper atmosphere.

Binotto, who has dedicated over a decade to photographing these elusive occurrences, noted, “Since I started more than 10 years ago, I have photographed hundreds of sprites. ELVEs, on the other hand, only three — including this one, which is a double event of sprites and ELVEs.” His passion and expertise shine through in his work, showcasing the intricate details of these rare atmospheric displays.

The phenomenon of ELVEs was first discovered in 1990 during the Space Shuttle Discovery’s mission to send the Ulysses probe to study the Sun. These flat structures can extend for hundreds of kilometers in the ionosphere, and Binotto likened their appearance to the “Alien Mothership” from the film Independence Day. Sprites, first photographed in 1989, are electrical discharges that rise into the atmosphere, reaching altitudes of 50 to 90 kilometers (30 to 55 miles), which is close to the conventional edge of space.

Both ELVEs and sprites are characterized by their striking red color, which results from the excitation of nitrogen particles in the upper atmosphere. This phenomenon is not only visually stunning but also scientifically significant, as it occurs in conjunction with thunderstorms and remains a subject of ongoing research due to its elusive nature.

The challenges of capturing these fleeting moments cannot be overstated. Both ELVEs and sprites last only milliseconds, making them difficult to photograph. Binotto has modified his camera for astrophotography, enhancing its sensitivity to infrared light, which plays a crucial role in capturing these atmospheric wonders.

For aspiring photographers interested in exploring this captivating field, Binotto encourages them to seek out resources that explain the phenomena and offer guidance on how to photograph them. “If someone wanted to start now, it is much easier than when I began. Back then, there was nothing that explained how to do it,” he remarked.

As we reflect on Binotto’s awe-inspiring work, we are reminded of the vast and mysterious world that exists above us. The dual event of the ELVE and sprite serves as a testament to the beauty of our planet’s atmosphere and the ongoing quest to understand the natural phenomena that surround us. May we continue to witness and document these extraordinary events in the years to come.
