Evaluation of video evidence of possible ball lightning
Quarterly Journal of the Royal Meteorological Society, Volume 151, Issue 772, October 2025 Part A.We analyze images of possible ball lightning that appeared less than 10 m from a video camera. The objects' velocity and estimated brightness all agree with typical eyewitness accounts of ball lightning. Though there is an alternative explanation that the objects were sparks from a power‐line arc, we describe analytical techniques that assist in ...
