The distance for this type of photo must be between 100 and 600km. From what is said in the world of experts in the sector, it is the best photo ever taken of this phenomenon. The photo shows an Elve's (emission of light and very low frequency perturbations due to electromagnetic pulse sources). It is a rare species of Sprite discovered in 1990 by cameras on board the space shuttle and forms above thunderstorms with very powerful lightning.

The shot was taken on March 27 at 21.43 UTC from Possagno, TV, Italy. The lightning that triggered it was in Polverigi, AN, Italy, at 285 km as the crow flies. It was so strong that it generated an intense electromagnetic pulse. The red ring marks where the pulse hit the Earth's ionosphere. Normal lightning carries 10 to 30 kiloamperes of current; this bolt was about 10 times stronger than normal (410 kA kilo-Ampère).

The duration of the "lightning" is about one millisecond, the "donut" has a diameter measured of about 360 km and a height above the ground of about 90/100km.

The photo was taken using tools dedicated to this type of shooting: a Sony A7S high-sensitivity camera defiltered at ISO 51,200; Nikon 20mm 1.8 lens wide open; 1/25 sec. Atomos Ninja Flame external recorder at 4K.
