Ball Lightning

If ball lightning is just electrical in nature, you wouldn't expect it to produce ionizing radiation. An ordinary flash of lightning happens very quickly, but ball lightning can last minutes. Ordinary ball lightning would not be associated with other hitch hiker phenomena that it was reported with. Would this phenomenon need to be intelligent? Not necessarily. Things can follow you home without having human level intelligence. But some of the phenomena reported at skinwaker ranch like humanoid appearing beings using technology would seem to display qualities of intelligence.
