The lightning itself cannot be seen by the spectator, so it appears as only a flash, or a sheet of light. The lightning may be too far away to discern individual flashes.
High-speed videos (examined frame-by-frame) show that most negative CG lightning flashes are made up of 3 or 4 individual strokes, though there may be as many as 30. [70] Each re-strike is separated by a relatively large amount of time, typically 40 to 50 milliseconds, as other charged regions in the cloud are discharged in subsequent strokes.

A storm chaser recorded footage of lightning flashing from an isolated thunderstorm as the sun set in Tonopah, Arizona, on June 24.Video recorded by Mike Olbinski shows a pastel sky during sunset ...
Pockels (1897) estimated lightning current intensity by analyzing lightning flashes in basalt (c. 1900) [12] and studying the left-over magnetic fields caused by lightning. [13] Discoveries about the electrification of the atmosphere via sensitive electrical instruments and ideas on how the Earth's negative charge is maintained were developed ...
