I am an electrical engineering professor with a research interest in ball lightning. For those unfamiliar with ball lightning, it is a glowing sphere usually under a foot in diameter that forms typically near thunderstorms (both outdoors and indoors sometimes), drifts around for a few seconds, and then vanishes or explodes. There is currently no good scientific understanding of it. People who chase storms should have a better than average chance of seeing ball lightning. If anyone reading this has seen ball lightning, here is my request: go to our ball lightning report website,, and fill out the questions there, and let us know that you heard about our site through Stormtrack. We are especially interested in any eyewitnessed photographs of something that might be ball lightning.
