Ball Lightning (BL) reports are hundreds of years old Causing amazement, bewilderment, fear, even death Most reports during thunderstorms BL floats along (often downwards)
BL is easily bright enough to be seen in daylight
In 1753, Russian scientist Georg Richmann was killed while trying to trap lightning, possibly by ball lightning according to descriptions lightning lightning,
