Have you ever experienced a phenomenon for which there appeared to be no logical explanation?   Many years ago, sometime around 1950, my family and I were driving south on a highway near Raleigh, North Carolina.  We were coming out of a rainstorm, and suddenly a white ball slowly dropped from the sky and landed on an automobile that was approaching us in the opposite lane.  There was the sound of an explosion, and the white ball disappeared.  I looked in the rearview mirror and saw that car had suffered no apparent effect and was continuing on its way.

I never saw anything like that before or since.  I researched the subject and found that what I probably witnessed is known as ball lightning,  an unexplained and potentially dangerous atmospheric electrical phenomenon. Ball lightning appears as a luminescent, spherical object that varies from pea-sized to several meters in diameter. Though usually associated with thunderstorms, the phenomenon lasts considerably longer than the split-second flash of a lightning bolt; and, in accordance with my own observation, reports have said that the ball eventually explodes.

Have you ever observed ball lightning?  Evidently it is extremely rare.

Another phenomenon that I observed only once was a waterspout.  I lived by the ocean for many years, and sightings of waterspouts have been reported by many people, but my only observation of a waterspout occurred in 1940-41 off the coast of Carolina Beach, North Carolina.  Actually I saw three well-formed waterspouts spinning along some five to ten miles off shore.  I watched them for some time before they disappeared from view.

Have you ever seen a waterspout?

What unusual observations can you report? 

Flying saucers, anyone?
