When conducting experiments on the electric explosion of titanium foil in water, a “strange” radiation was detected, leaving dotted traces on the film. The velocity of the carriers of this radiation was estimated as 20–40 m/s, and their energy,

Observations of eyewitnesses are the main source of data on ball lightning (BL) properties, but often their descriptions turn out to be incomplete, contradictory and lacking in details. Recently due to the wide use of digital camcorders, still camera

There is still no complete understanding of the optical radiation of ball lightning. So far no explanation has been found for the variety of its colors, the reasons for the change of color, the generation of light flashes etc. This may be due to inco
