Quote:Ball lightning has been described as transparent, translucent, multicolored, evenly lit, radiating flames, filaments or sparks, with shapes that vary between spheres, ovals, tear-drops, rods, or disks.[12]
Ball lightning is often erroneously identified as St. Elmo's fire. They are separate and distinct phenomena.[13]
The balls have been reported to disperse in many different ways, such as suddenly vanishing, gradually dissipating, being absorbed into an object, "popping," exploding loudly, or even exploding with force, which is sometimes reported as damaging.[10] Accounts also vary on their alleged danger to humans, from lethal to harmless.
