Ball lightning is a 'singular, luminous, persistent, and relatively small globular mass'.
At present there is no fully satisfactory or generally accepted scientific theory of ball lightning. I obtained my MPhil degree from the University of London for research in this area and continue to maintain an active interest. I specialise in the study of ball lightning events, especially recent ones or those involving traces or damage. I would like to be informed of new ball lightning theories and relevant conferences or other events. I am also happy to deal with enquiries about ball lightning.
