The lightning that triggered it was in Polverigi, AN, Italy, at a distance of 285 km. Its strength, estimated at about 410 kA (kilo-Ampère), which is an order of magnitude stronger than a normal lightning (10 to 30 kilo-Ampère), generated an intense electromagnetic pulse. The red ring marks where the pulse hit the Earth's ionosphere.
Plasma temperatures in lightning can approach 28,000 kelvins. Atmospheric electricity describes the electrical charges in the Earth's atmosphere (or that of another planet). The movement of charge between the Earth's surface, the atmosphere, and the ionosphere is known as the global atmospheric electrical circuit.

"At this key he charged phials, and from the electric fire thus obtained, he kindled spirits, and performed all other electrical experiments which are usually exhibited by an excited globe or tube." Contrary to popular belief, the kite was not hit by visible lightning; otherwise Franklin would almost certainly have been killed.
